Kelly Bryant started Clemson's first four games of the 2018 season at quarterback. Then Dabo Swinney named the freshman Trevor Lawrence as his starter, and within days Bryant had left the team. He was not giving up football. A rule the NCAA had adopted that summer let a Division I player appear in four games and still keep the season, and Bryant had played in exactly four. He kept his last year and spent it at Missouri.
That was the redshirt rule at its most visible. A redshirt, under the NCAA Division I Manual, was a year a player spent on the roster without using one of his four seasons of competition, and he had five calendar years from first enrolling full time to play those four. The four-game allowance arrived in 2018, and a medical hardship waiver covered players hurt early in a season. In June 2026 the Division I Cabinet voted to replace the whole arrangement with five seasons of competition inside five years. Under that model there is nothing left to redshirt, because every year on the clock is a year a player may play. Players already in college sit in a changeover in which either set of rules can apply. The new one governs alone for those who first enroll from fall 2027.
What a redshirt was under the four-in-five rule
Search the Division I Manual for the word and it barely appears. The redshirt was never a status the NCAA granted. It was the gap between two numbers in the eligibility bylaws: four seasons of competition, and a five-year period in which to use them. Five minus four leaves one, and that spare year is all a redshirt ever was.
The five-year clock started the first time a player enrolled as a full-time student at any college, and it did not stop. Not for a transfer, not for a semester off, not for an injury. The seasons were counted separately. A player used one the moment he took part in a game against outside competition, and until 2018 "took part" meant a single play. A freshman sent out to cover one kickoff in a blowout had spent a quarter of his career.
So a redshirt year looked like this. The player was enrolled, often on scholarship, and did everything his teammates did from Sunday to Friday. He lifted, sat in position meetings, practiced, and went to class. On Saturdays he dressed for home games and stood on the sideline, or watched from the stands in a team polo. He did not play. At the end of the fall he had used one year of clock and no seasons, and the next year's roster listed him as a redshirt freshman.
Two details were commonly misunderstood. First, nobody had to declare a redshirt in August. The decision was simply the fact of not having played by December, which let coaches keep a freshman available all season in case of injuries above him. Second, the year did not have to be the first one. A junior who lost his job, or a transfer learning a new offense, could sit out a later season and take the spare year then. He could do it only once, because there was only one spare year on the clock.
Reading the roster labels
Rosters carried two classes for these players, the academic one and the athletic one. "RS So." meant a redshirt sophomore: third year on campus, second season of competition. A fifth-year senior and a redshirt senior were the same person. The labels mattered to professional scouts for a practical reason, since a player becomes eligible for the NFL draft three years after high school graduation regardless of how many seasons he has played. A redshirt sophomore could leave for the draft, and plenty did.
Where the rule stands after the June 2026 vote
In June 2026 the Division I Cabinet approved a new eligibility model. The short version is five seasons in five years. A player's clock still runs for five years, but all five can now be seasons of competition.
The consequences follow from the arithmetic. With five seasons inside a five-year clock there is no spare year, so there is no redshirt. Most of the waivers that used to stretch a career go with it. What survives is a short list of clock exceptions that existed under the old manual too, for military service, religious missions and pregnancy.
The second change is how the clock starts. It used to begin only at full-time enrollment. Now it begins at full-time enrollment or at the start of the academic year after a player's 19th birthday, whichever comes first. The age trigger was the most argued part of the package, because in sports such as men's ice hockey and men's basketball players commonly arrive older.
| Feature | Old Division I model | Model approved June 2026 |
|---|---|---|
| Seasons of competition | Four | Five |
| Length of the clock | Five calendar years | Five years |
| What starts the clock | First full-time enrollment at any college | Full-time enrollment or the academic year after the 19th birthday, whichever is sooner |
| Redshirt year | One spare year available | None; every year can be played |
| Season-ending injury early in the year | Medical hardship waiver could return the season | No medical redshirt |
| Football's limited-participation rule | Up to four games without using a season | No longer needed |
| Clock exceptions | Military service, religious missions and pregnancy among them | Military service, religious missions and pregnancy retained |
One caution belongs here. The vote set the framework, and the detailed interpretations that compliance offices work from tend to follow a decision like this over months. A player or parent with a specific case should take it to the school's compliance staff and not rely on a general guide, this one included.

Players already in college, and what redshirt sophomore still means
The changeover rule is generous, and it has a hard edge.
Players caught in the changeover, those already enrolled and those arriving before the new model applies in full from fall 2027, are assessed under whichever model is more advantageous to them. That is an individual test. A compliance office looks at one player's history and works out which set of rules leaves him more football.
For many players the two answers are the same. Take someone who enrolled in fall 2023, redshirted that year and played in 2024 and 2025. Under the old model he has two seasons left and a clock that runs through the 2027 season. Under the new one he has five seasons inside the same five years, has used two, and can play in 2026 and 2027. No difference.
Now take his classmate who played as a true freshman in 2023 and in both seasons since. The old model gives him one more season, 2026, and then he is finished with a year of clock unused. The new model lets him play that fifth year in 2027. He gains a season. The players for whom the old model may be the better one are those holding a waiver the new rules no longer offer, such as a clock extension granted for earlier injuries. Those worked examples are a plain reading of the framework, not a ruling, and edge cases are exactly what the follow-up guidance exists to settle.
The hard edge: the changeover protects players who still had eligibility to use. A player who had already exhausted his four seasons under the old rules before the new model arrived should not expect it to reopen his career, and anyone in that position needs a compliance office's reading, not a general guide's.
The label outlives the rule for a few seasons
Rosters in the transition years still say "redshirt sophomore" and "redshirt junior," because those players took the year when it existed and schools still track seasons used against years enrolled. The labels will thin out as those classes leave. A freshman who enrolls in fall 2027 will never be a redshirt anything. He will be a first-year player, then a second-year player, and a fifth-year senior if he stays, and the expectation is that media guides drift toward listing year in program.
The four-game redshirt rule of 2018 and its 2024 postseason fix
Before 2018 the choice was all or nothing, and coaches hated it. A freshman tackle who had practiced for three months could not be used in the bowl game without spending a full season on sixty snaps. A team with injuries at linebacker in November had to decide whether one emergency start was worth a year of a teenager's career.
The American Football Coaches Association pushed for relief, and the Division I Council approved it in June 2018. A football player could appear in up to four games in a season and not be charged with a season of competition. Any four. They did not have to be the first four or come at the end, and they did not have to be consecutive.
The rule did what its sponsors wanted. Freshmen got live snaps late in the year, staffs could audition players in bowl games, and depth problems were patched without long-term cost. It also did something nobody had campaigned for. A veteran who lost his starting job in September could stop at four games, keep the year and transfer, which is what Bryant did within months of the rule taking effect. Four games out of a twelve-game regular season is a third of it, and that was enough time for a player to learn where he stood. For how those twelve games and the postseason add up, see our count of how many games a college football team plays.
Why the postseason stopped counting
The four-game limit originally covered every game. Then the schedule grew. With conference championship games and an expanded College Football Playoff bracket, a team could play four or five games after the regular season ended. A freshman who had been carefully held to four appearances would have been unavailable for the most important month of the year, or would have burned the season by playing in it.
In 2024, early in that season, the NCAA changed the count. Conference championship games, bowl games, the College Football Playoff and the FCS playoffs no longer counted toward the four. From then on the limit applied to regular-season games only, and a first-year player could appear in four of those and every postseason game besides.
The four-game rule lasted eight seasons as the working definition of a redshirt. For players who start under five-in-five it has no job left to do.
The medical redshirt rule, and why a sixth year was always rare
"Medical redshirt" was the press-box name. The manual called it a hardship waiver, and it was narrower than the nickname suggested.
A hardship waiver gave a season of competition back to a player whose year ended through injury or illness. Three conditions had to be met, and missing any one of them sank the application.
- The injury ends the seasonThe injury or illness has to be incapacitating for the rest of that season, shown by medical records made at the time and not written afterward.
- It happens in the first halfThe injury must occur before the midpoint of the team's season. A player hurt in the ninth game of twelve did not qualify.
- Limited games playedThe player must not have competed in more than 30 percent of the team's scheduled games, a figure rounded up to four on a 12-game schedule.
- Conference reviewThe school files the paperwork, and for most cases the conference office, not the NCAA national office, decides it.
- The season comes backIf granted, the season is not counted against the player's four. The five-year clock keeps running.
The conditions the Division I Manual set for returning a season of competition to an injured player under the old four-in-five model.
That last step is where the sixth year got hard. A hardship waiver returned a season. It did not add time. A player who had never redshirted could tear a knee in September, receive the waiver, and still fit four seasons inside his five years, with the injury year serving as the spare.
A player who had already redshirted by choice was in a different position. Year one, redshirt. Year three, a torn ligament in the second game. He could get the season back, but his clock would expire with only three seasons played. To get the fourth he needed something else: an extension of the five-year clock, a separate request that went to the NCAA. The standard for that was two seasons lost for reasons beyond the player's control. A voluntary redshirt was a coach's decision, not a circumstance beyond anyone's control, and it did not count as one of the two.
So sixth years went mostly to players with two documented, season-ending injuries. They were uncommon enough that each one made news in its conference. The new model ends redshirts and most of the waivers that stretched careers, and the medical redshirt as a way of adding a season goes with them. That is the harshest line in the reform, and the trade the Cabinet made for it is that every player now gets the fifth season up front, without having to prove anything.
Why coaches used the redshirt year
An offensive tackle leaves high school at 18 weighing perhaps 265 pounds. The defensive ends he will face in a Big Ten or SEC game are 22 and have spent four years in a college weight room. Coaches did not redshirt linemen out of caution. They did it because the physical gap was real and a year of strength training and regular meals closed much of it. Offensive line was the position where redshirting came closest to automatic.
Quarterback was the other classic case, for a different reason. There is one job, the playbook takes time, and a year behind an established starter cost nothing. Johnny Manziel sat out 2011 at Texas A&M and won the Heisman Trophy in 2012. Jameis Winston redshirted at Florida State in 2012 and won it in 2013. Both were redshirt freshmen, a phrase that sounded like a contradiction to anyone hearing it for the first time on those broadcasts. Our guide to how the Heisman vote is counted covers the award itself.
Elsewhere the decision came down to the depth chart. A freshman safety behind three seniors was a redshirt. The same player on a team with injuries in the secondary was covering punts by October. Highly rated skill players, the ones at the top of the recruiting star ratings, redshirted least often, because they could help immediately and many planned to leave for the NFL after three years anyway.
A year on the scout team
The redshirt's working life was the scout team. Each week the scout offense learned the upcoming opponent's plays off laminated cards held up by a graduate assistant and ran them against the first-team defense. A redshirt receiver might wear a different jersey number every week, the number of the opposing team's best wideout. The work was unglamorous and useful, and staffs took it seriously enough to name a scout team player of the week.
Redshirts generally did not travel to away games. They lifted on a heavier schedule than the players who had to be fresh on Saturday, since they had no game to recover for. In April they got their first real audition, which is one reason the spring game mattered more to second-year players than to anyone else on the roster.
There was an academic argument as well, and it was more than cover. Five years is a more realistic timetable for a degree alongside a Division I football schedule, and many fifth-year players were graduate students by their last season.
Grayshirts, blueshirts and greenshirts
None of these three was ever an eligibility category. They were recruiting and scholarship maneuvers that borrowed the redshirt's naming convention, and all of them grew out of limits that have since been repealed or replaced.
| Term | What the player did | What it accomplished |
|---|---|---|
| Redshirt | Enrolled, practiced all year, did not play, or played four games or fewer from 2018 | Kept a season of competition; the five-year clock still ran |
| Medical redshirt | Suffered a season-ending injury early and received a hardship waiver | Got the season back; the clock still ran |
| Grayshirt | Delayed full-time enrollment, usually from August to January | Kept the clock from starting and moved him into the next recruiting class |
| Blueshirt | Arrived as a walk-on who had not been formally recruited, then received a scholarship | Counted against the following year's signing limit |
| Greenshirt | Finished high school a semester early and enrolled in January | Took part in spring practice before his first season |
The grayshirt existed because of the annual cap on new scholarship players, which stood at 25 for most of the modern era. A school with more commitments than places would ask one recruit to wait. He stayed home for the fall, or took a part-time class load at his own expense, and enrolled in January on scholarship as a member of the next class. Because he was not a full-time student in the fall, his clock had not started. Handled honestly, with the plan explained months ahead, a grayshirt suited some players, especially those recovering from a senior-year injury. Sprung on a recruit shortly before National Signing Day, it was among the uglier practices in recruiting.
The blueshirt was cleverer. NCAA rules defined a "recruited" player by specific acts: an official visit, in-person contact at his home, a written scholarship offer. A player who had received none of those could enroll as a walk-on, start practice, and be put on scholarship days later, with that scholarship charged to the next year's count. The mechanics sit closer to walk-on status than to eligibility, and our guide to what a walk-on is follows them further.
A greenshirt gave up his last semester of high school, the prom and the spring sports season included, to go through winter conditioning and spring practice. Nothing about his eligibility was unusual. Early enrollment is now so common among top quarterbacks that the color has mostly dropped out of use.
The annual signing cap has since gone, and with the roster limits that replaced scholarship counts in 2025 the reason for grayshirts and blueshirts went too. The age trigger in the new clock closes what was left of the grayshirt's logic, since a player can no longer hold his clock still indefinitely by staying out of school.
How the new five-year clock starts
Two events can start it, and whichever comes first controls.
- Full-time enrollmentA player who enrolls full time at a college starts his clock then, as under the old rule. This is the trigger for most high school recruits.
- Or the age triggerIf he has not enrolled, the clock starts at the beginning of the academic year after his 19th birthday.
- Whichever is soonerThe earlier of those two dates controls. Delaying enrollment no longer holds the clock in place.
- Five years runThe clock runs for five years, and each of them can be a season of competition.
- Recognized exceptionsTime away for military service, a religious mission or pregnancy is treated separately and does not use up the clock in the ordinary way.
The trigger approved by the Division I Cabinet in June 2026. Earlier of the two events controls; the listed exceptions can pause the clock.
The age trigger is the new idea. Under the old manual a player's clock began only when he became a full-time student, so anything he did beforehand was free. A year at a prep school, a year of junior hockey, a couple of seasons in a European basketball academy: none of it touched his five years. The result in several sports was 21-year-old freshmen, and a rulebook that treated two players of the same age very differently depending on what they had done at 18. Tying the clock to a birthday puts a ceiling on that.
Football feels this less than hockey or basketball do. The typical recruit turns 18 during his senior year of high school and enrolls that summer, so the enrollment trigger comes first and the age trigger never matters. It bites at the margins: the grayshirt, the player who spends a postgraduate year at a prep school, the junior college late bloomer, the older international specialist. What the rule means for that last group, including the Australian punters who have arrived in American programs in their twenties for more than a decade, is among the questions the first rounds of guidance will have to answer. We would not guess at it here.
The exceptions that survived
Three were kept. Military service pauses the calculation, which matters to the service academies and to veterans who enroll after enlistment. Religious missions are protected too, a provision that programs such as BYU and Utah have relied on for generations, with players leaving for two years and returning older and often heavier. Pregnancy remains grounds for relief.
Everything else that used to be argued case by case is, in principle, gone. The clock does not pause for a transfer, for an injury, for a coaching change or for a semester away from school.
What five-in-five changes for rosters, courts and recruits
The average college football player is about to get older. Under four-in-five, a fifth-year senior was someone who had redshirted, been hurt, or both. Under five-in-five, a fifth year is simply available to anyone a program still wants. Expect two-deep charts with more 23-year-olds on them.
The second effect is in the courtroom, and it explains a good deal of the reform. In December 2024 a federal judge in the Middle District of Tennessee granted Vanderbilt quarterback Diego Pavia an injunction against the NCAA rule that counted his junior college seasons toward his four. The court found the restriction likely violated antitrust law, in part because of the name, image and likeness income a further Division I season would bring. The NCAA responded with a blanket waiver for players in similar positions for 2025-26. Other players then sued over other limits, with mixed results in different courts. Each discretionary waiver the NCAA granted or refused had become a potential lawsuit.
A rule built on a birthday and a fixed number of years gives a judge less to pick at than a system of case-by-case exceptions. Our judgment is that five-in-five is a legal strategy at least as much as an educational one. That does not make it a bad rule. A bright line that every player can read for himself has real value, and the old waiver system was slow and produced results that looked arbitrary from outside.
Who gets squeezed
High school seniors, first. Every roster place taken by a fifth-year player is one not offered to a recruit, and football rosters are now capped. The numbers behind that are in our guide to college football scholarship limits. A coach choosing between a 23-year-old guard with 30 starts and an 18-year-old who needs two years of development has an easy decision, particularly when the veteran can be found in the transfer portal every winter.
The developmental year changes character rather than disappearing. A freshman lineman who is not ready will still spend his first fall on the scout team. He just will not get the year back. On the other side of the ledger, coaches no longer have to count a freshman's appearances in November, and a first-year player who earns snaps can take them without anyone doing arithmetic.
The NFL draft rule is untouched. Players are eligible three years after high school, so the best of them will still leave after three seasons. The fifth season is mostly for everyone else, and with NIL money attached to a starting job it is worth more than it used to be.
The 2020 season that did not count
College football has already run a version of this experiment. In August 2020, with the Big Ten and Pac-12 having postponed their fall seasons and other leagues pressing ahead through the pandemic, the Division I Council gave every fall-sport athlete an additional season of competition and an additional year in which to use it. It applied whether a player's team played twelve games or none. In effect the 2020 season did not count against anyone.
The decision was fair, and its consequences ran for half a decade. A true freshman in 2020 could play that year for free and then four more, through 2024. Add a conventional redshirt and he was still eligible in 2025. Sixth-year seniors stopped being unusual. Players who combined the free year with a redshirt and a medical waiver reached seven.
The outer limit was Cam McCormick, a tight end who enrolled at Oregon in 2016, lost most of four seasons to injuries, and finished his career at Miami in 2024. It was his ninth season of college football. Nobody designed a system to produce that. It was what happened when a redshirt, repeated hardship waivers, clock extensions and the pandemic year were stacked on one player.
Rosters swelled during those seasons. The NCAA let returning seniors be carried above the usual scholarship limit for a year so that an older player's extra season did not cost a freshman his place. Coaches found they liked having 23- and 24-year-olds on the offensive line. Athletic directors found the bill larger.
By the time the last pandemic-year players left, programs had spent five seasons treating a fifth year of competition as normal. That experience made the 2026 vote easier. Five-in-five is close to the 2020 arrangement made permanent, with the waivers stripped out so that five cannot grow into seven again.
Outside Division I, where a redshirt still exists
The June 2026 vote was a Division I vote. It does not rewrite the manuals of Division II or Division III, and it has no authority over the NAIA or the junior colleges, each of which counts seasons in its own way. Anyone following a player at one of those levels should read that level's rules and not assume the Division I answer.
| Level | How eligibility is counted | Redshirt position |
|---|---|---|
| NCAA Division II | Four seasons within ten semesters or fifteen quarters of full-time enrollment | Exists; a year without competition does not use one of the four seasons |
| NCAA Division III | Four seasons within ten semesters or fifteen quarters of full-time enrollment | No conventional redshirt; practicing with the team after the first game counts as a season of participation |
| NAIA | Four seasons within ten semesters or fifteen quarters of attendance | A year without competition does not use a season |
| NJCAA junior colleges | Two seasons of competition | A year without competition does not use a season; hardship rules apply |
The structural difference is that Division II, Division III and the NAIA count terms of enrollment, not calendar years. A Division II player who leaves school for a year does not burn any of his ten semesters during that year. A Division I player's clock, old model or new, runs straight through.
Division III is the outlier on redshirts. Its membership decided long ago that holding players out to extend their careers did not fit a division with no athletic scholarships, and wrote the rule so that practice counts. A Division III player who practices after his team's first game has used one of his four seasons whether he plays or not. Medical hardship relief exists there, but the scout-team redshirt year does not.
Junior college is where the old and new worlds collide. NJCAA players get two seasons, and the NCAA has traditionally counted those seasons against a transfer's Division I total, the rule at issue in the Pavia case. How junior college time is treated under a clock that starts at enrollment or at 19 matters a great deal to players taking that route, and the differences between the subdivisions they transfer into are set out in our comparison of FBS and FCS football.
Where the word redshirt came from
Lincoln, Nebraska, 1937. Warren Alfson was a lineman from Wisner, a small town in the northeast of the state, and he could see the depth chart in front of him. Nebraska had experienced players at his position and he was not going to play much. He asked the coaches whether he could spend the season practicing with the team without appearing in games, and they agreed.
Alfson worked out that fall in a red Nebraska jersey with no number on it. The plain shirt marked him as someone who was with the team but not of the game-day squad, and the term came from the shirt. He returned to competition afterward, and by 1940 he was an All-American guard on the Nebraska team that went to the Rose Bowl.
The practice spread because it worked, and because the eligibility rules of the era allowed it without anyone having intended to. One detail from that period explains why the phrase "redshirt freshman" came much later. For most of the century freshmen could not play varsity football at all; the NCAA did not make them eligible until 1972. The original redshirts, Alfson among them, were sophomores and juniors holding back a varsity season. Only after 1972 did the first year on campus become the natural one to sit out, and the redshirt freshman become a standard line on a roster.
The red jersey itself outlived its origin in another form. Scout-team and held-out players wore contrasting practice jerseys in many programs for decades, though the color varied and red eventually came to mean something else on most practice fields: a quarterback who is not to be hit.
The word has traveled well beyond football. Parents talk about "redshirting" a kindergartner with a summer birthday, holding the child back a year to be older and bigger than classmates, which is precisely what Alfson's coaches were doing with a lineman. For more on the game at every level, our American football hub collects the rest of the site's coverage. In Division I the rule that gave the word its meaning is on its way out. The word will probably stay.
