NFL Delay of Game Penalty: The Rule for Offense and Defense
The NFL delay of game penalty costs five yards when the play clock runs out before the snap, and the same rule punishes stalling by a defense too.

An NFL delay of game penalty costs five yards, and the down is played again. The rule is in Rule 4, Section 6 of the NFL rulebook. An offense has 40 seconds from the end of the previous play, or 25 seconds after an administrative stoppage, to snap the ball. If it does not, the back judge blows his whistle, the ball stays dead and the offense goes back five yards. There is no loss of down. The same section punishes stalling in other forms and by either team: lying on a tackled runner, spiking the ball after an ordinary play, a defender twitching at the line to draw a false start. Each of those is five yards as well.
Detroit fans know the rule from the call that never came. Justin Tucker's 66-yard field goal at Ford Field on September 26, 2021, struck the crossbar, bounced over and beat the Lions 19-17 with no time left; it stood as the NFL's longest field goal until November 2025. On the snap before it, the play clock behind the end zone showed zero before Baltimore's center moved the ball, no flag came, and the Ravens threw an incompletion that left three seconds for the kick.
The NFL delay of game penalty in its usual form: the play clock reaches zero
Nearly every delay flag a viewer sees is the same event. The offense is late. A substitution took too long, the play call came in garbled, the quarterback spent eight seconds changing the protection, and the clock on the wall beat the center's hands.
The rulebook states it in a single line: it is a delay of the game if the ball is not put in play by a snap within 40 seconds after the start of the play clock. A second article substitutes 25 seconds after certain stoppages. Which count applies and when it starts is the subject of our guide to the NFL's play clock rules; this page is about what happens when the count is lost.
What happens is short. Article 4 says the back judge shall blow his whistle for the foul and the ball remains dead. Nothing that follows the whistle counts. A quarterback who takes the snap a half-second late and throws a touchdown has thrown nothing.
| Before the foul | After a delay of game |
|---|---|
| First-and-10 at the offense's 30 | First-and-15 at the 25 |
| Second-and-7 | Second-and-12 |
| Third-and-1 | Third-and-6 |
| Fourth-and-goal at the 2 | Fourth-and-goal at the 7 |
| First-and-10 at the offense's own 4 | First-and-12 at the 2 |
The last row is half the distance to the goal, which the rulebook applies to every distance penalty. The down does not change in any of them.
- 40Seconds on the standard play clock
- 25Seconds after an administrative stoppage
- 5Yards for delay of game
- 15Yards for a second straight delay on one down
From Rule 4, Section 6 and Rule 12, Section 3 of the NFL rulebook. The 15 yards apply to a second successive delay on the same down with the game clock running.
A delay is often the cheapest foul on the penalty sheet and occasionally the most expensive. Five yards on first down is a nuisance. Five yards on third-and-1 turns a sneak into a pass, and on fourth-and-goal it usually turns a touchdown attempt into a field goal.
The back judge's mechanic: eyes on the clock at zero, then down to the ball
One official is responsible for this foul and he stands deep in the middle of the field, behind the linebackers and safeties. The back judge cannot watch the play clock and the football at once. They are in different places. So the league's mechanic gives him a sequence: watch the clock as it winds down, and when it shows zero, drop the eyes to the ball. If the ball is being snapped as he finds it, play on. If it is sitting on the ground, whistle.
That glance takes time. Not much, perhaps a few tenths of a second, but it is built into every delay decision ever made in the league. An offense is not flagged at 0.0. It is flagged if the ball has not started moving by the time a man who was looking somewhere else looks at it.
- Clock winds downThe back judge, positioned deep behind the defense, watches the play clock as it approaches zero.
- Zero showsHe shifts his eyes from the clock to the football at the line of scrimmage.
- Ball is movingIf the snap has started when he finds the ball, there is no foul and the play continues.
- Ball is stillIf the ball has not been snapped, he blows the whistle and throws the flag. The ball stays dead.
- EnforcementThe referee marks off five yards from the succeeding spot, the down is replayed and the play clock is reset to 25.
The sequence follows the officiating mechanic for the back judge and Rule 4, Section 6, Article 4. The step from clock to ball is where the unflagged late snap comes from.
This is why television regularly shows a zero on its graphic with the ball still on the ground and no penalty. Two things are going on. The broadcast graphic is a feed of the stadium clock and is not guaranteed to be frame-perfect with the picture beside it. And even when it is, the mechanic allows the beat.
Baltimore's snap in Detroit was that beat stretched to its limit and, on the broadcast at least, past it. The sequence described above is the only explanation the mechanic offers, and it satisfied nobody in Michigan.
A fair judgment is that the mechanic is the least bad option. A buzzer at zero, as basketball uses for its shot clock, would be exact, but a horn sounding as 22 players come off the ball is its own safety problem. A second official assigned only to the clock would cost the crew a pair of eyes somewhere else. The league has chosen a small, consistent lag in the offense's favor, and offenses have learned exactly how long it is.
Delay of game vs false start: two dead-ball fouls that look alike on the stat sheet
They sit next to each other in every box score. Five yards, offense, before the snap, down replayed. The difference is that one is a failure to act and the other is acting too soon.
| Delay of game | False start | |
|---|---|---|
| What happened | The ball was not snapped in time, or a player stalled | A set offensive player simulated the start of the play |
| Rule | 4-6 | 7-4-2 |
| Who rules on it | Back judge for the play clock | Usually the wing officials or the umpire |
| Who can commit it | Either team | Offense only |
| Yardage | 5, from the succeeding spot | 5, from the line of scrimmage |
| Referee's signal | Arms folded in front of the chest | Forearms rotated over each other in front of the chest |
Both stop the game clock, and that is where the rulebook has had to be careful. A foul that stops the clock is useful to a team that needs time, and a foul that lets it restart is useful to a team that wants to burn it.
After the two-minute warning of either half, an offensive foul that stops a running clock during a dead-ball period costs ten seconds off the game clock in addition to the yards. A false start with the clock running is the usual trigger, and the delay section's own spike clause, covered below, is another.
Earlier in the fourth quarter the concern runs the other way, and it took two coaches in 2019 to show the league why. That story has its own section below.
When the two arrive together, sequence decides. If the back judge's whistle for the expired clock came first, the flag is delay of game. If a lineman flinched while the play clock still had time on it, the flag is a false start and the clock never reached zero in any sense that matters. Either way it is five yards.
The movement fouls on either side of the line, and how officials decide which of them to call when two players flinch together, are sorted out in our guide to false start, offside and encroachment.
The rulebook's other delays: bodies on the ball, slow huddles and timeouts a team did not have
Article 5 of the section begins "other examples of action or inaction that are to be construed as delay of the game include, but are not limited to," and then lists seven. Four of them are administrative, and they are the ones fans rarely notice until one decides something.
Staying on a dead ball or a downed runner. A player who unnecessarily remains on the ball or on a tackled runner is guilty of delay. Late in a half this is the defense's temptation, and it gets a section of its own next.
The snapper who will not wait. A center may not snap the ball until the officials have had a reasonable time to reach their positions. The first time it happens the ball simply stays dead and the crew issues a warning. The rule says "repeatedly," and a repeat is five yards. This is the brake on hurry-up offenses that try to snap while the umpire is still backpedaling.
Slow assembly after a timeout. Either team can be flagged for undue delay in getting back to the line once a timeout has ended. A team still huddled at the sideline when the referee is ready has no excuse the rulebook recognizes.
A timeout the team was not entitled to. Each team gets three per half. A second timeout by the same team in one dead-ball period is prohibited, and so is a fourth in a half. The rulebook tells officials to ignore such requests. When one is granted by mistake, the result is five yards for delay and the timeout is still charged. A defense trying to freeze a kicker with a second straight timeout gets no such leniency; that request is unsportsmanlike conduct whether or not it is granted. What a team may legally do with its three is covered in our guide to NFL timeout rules.
Excess timeouts for injuries
There is one more route to the same flag. After the two-minute warning, a team with no timeouts left whose player goes down hurt is charged an excess timeout. The first one in a half is free of yardage. The second and each one after it costs five yards for delay of game, on the theory that a team repeatedly stopping the clock with injuries it cannot pay for is delaying the contest, whatever the cause. The rulebook attaches a note saying that the Competition Committee deprecates feigned injuries and urges coaches to discourage them, which is as close as the document comes to raising an eyebrow.
The words "but are not limited to" matter. The list is illustrative. A referee who sees a team deliberately holding up the game in a way the book did not anticipate has the authority to call it.
Delay of game on the defense: abrupt movements and hands on the football
Two of the seven listed acts were written with defenders in mind, and a third is theirs most of the time.
The twitch at the line
A defensive player aligned in a stationary position within one yard of the line of scrimmage may not make quick and abrupt actions that are not part of normal defensive movement and are an obvious attempt to cause an offensive player to false start. The whistle is immediate. The penalty is five yards against the defense.
The rule draws its own boundary. A defender who is walking or running toward the line to time the snap and stops abruptly because the ball was not snapped has not fouled. So a linebacker timing a blitz is safe, and so is a lineman shifting from one gap to another, which is ordinary movement. What is banned is the stationary man who stamps, jerks his shoulders or throws his hands forward with no purpose except to make a guard jump.
Shouting is handled elsewhere and costs three times as much. Defensive acts or words designed to disconcert the offense at the snap, such as barking a fake cadence, fall under the unsportsmanlike conduct article at 15 yards. The reasoning behind the gap is not stated in the book. A plausible reading is that a twitch tests a lineman's discipline, and a counterfeit snap count sabotages the offense's means of starting the play at all.
Slowing the snap
The other defensive clause is intentional contact with the football or a player to delay the snap or the officials' ability to make the ball ready for play. Picture an offense hurrying to the line with the clock running and a defender who kicks the ball away from the umpire, or holds a receiver down by the jersey as he tries to get up, or stands over the ball as if he had not noticed it. Five yards.
Add the downed-runner clause and the picture is complete. In a two-minute drill the offense's scarcest resource is seconds, and a tackler who takes his time climbing off the ball carrier is spending them. The specifics of how offenses ration that time are in our explainer on the two-minute drill.
What the defense's five yards do not include
No automatic first down. Defensive delay of game is five yards from the succeeding spot and the down stays as it was, unless the yardage itself reaches the line to gain.
There is a clock protection, though. After the two-minute warning a defensive foul that stops the clock cannot be used to help the defense: the play clock goes back to 40, and the offense chooses whether the game clock restarts on the referee's signal or waits for the snap. In the last 40 seconds of a half the rule goes further and lets the half end on a clock-stopping defensive foul unless the defense has a timeout left or the offense elects to keep playing. A defense cannot foul its way to an extra possession.
Spiking or throwing the ball after a play: the five-yard reaction
A receiver makes a 19-yard catch on third-and-18, pops up and slams the ball into the turf. Flag. The crowd assumes taunting, and the referee announces delay of game.
The clause is one line: spiking or throwing the ball in the field of play after a down has ended, except after a score. The logic is mechanical. The officials need that football. It has to be collected, relayed to the umpire and set on the spot before the next play can start, and a ball that has been bounced 15 yards away or flung into the bench area holds everything up. The league treats the act as stalling, not as showmanship.
The exception is the score. After a touchdown there is no next snap waiting on that ball, and the end-zone spike is expressly outside the rule.
A few distinctions are worth having straight.
Handing or flipping the ball to an official is what the rule wants. Dropping it at the spot is fine.
The quarterback's clock-stopping spike is a different thing entirely. That is a live play: the ball is snapped and immediately thrown into the ground, and the rulebook carves it out of intentional grounding. It is an incomplete pass, not a delay.
Spiking the ball at or toward an opponent can be flagged as taunting, a 15-yard unsportsmanlike foul. The delay clause covers the player who was celebrating his own catch, not the one making a point to the cornerback.
Where the spike is enforced
Because the spike comes in the continuing action after the play, it is a dead-ball foul enforced from where the play ended, and the rulebook says that when the offense has just made a first down, it is first-and-10 after the yardage is walked off. So the 19-yard catch becomes a 14-yard gain and a fresh set of downs. Compare that with a play-clock delay on the next snap, which is a foul between downs and leaves the offense first-and-15.
After the two-minute warning the same spike is also listed among the acts that illegally conserve time. With the clock running, it costs the offense ten seconds as well as the five yards. A receiver who spikes the ball in bounds with eight seconds left and no timeouts has handed the defense the option of ending the half.
The deliberate delay: backing up a punter and walking away from a hard count
Fourth-and-2 at the opponent's 42-yard line. The offense comes to the line in a regular formation, the quarterback goes through a long, loud cadence, and nobody on the defense moves. The play clock runs to zero. Flag, five yards, and the punt team jogs on.
Nothing went wrong there. The offense never intended to snap the ball. It was fishing for a defensive jump that would have been worth five yards and a first down, and the delay of game was the planned exit. How quarterbacks build a cadence to make a lineman jump is covered in our guide to the hard count in football.
The offense accepts the penalty happily, because in that part of the field five yards backward helps a punter. A punt that reaches the end zone is a touchback and comes out to the 20. From the opponent's 42, a punter has only a short strip of grass in which to land the ball and stop it. From the 47 he has five more yards of room to hang it high and let his coverage down it inside the 10.
- Line up to goOn fourth-and-short the offense shows a normal formation and the quarterback starts a long cadence with no snap planned.
- Defense holdsNo defender enters the neutral zone. The offense lets the play clock run out.
- FlagThe back judge calls delay of game. The ball was never live and the down is unchanged.
- Defense decidesIt may accept, moving the punt back five yards, or decline, making the punter kick from the closer spot.
- PuntThe kicking team punts from whichever spot the defense chose.
A common sequence near midfield. The defense's decision in the last step is its right under the general rule that a penalty may be declined.
Why the defense sometimes says no
A penalty is an offer, and the offended team is not obliged to take it. Defensive coaches who understand the punter's arithmetic decline the delay and make him kick from the original spot, where a touchback is more likely. The referee announces that the penalty is declined, fourth down, and the punt team is left with the tighter kick it was trying to avoid.
It is one of the few situations in football where the team that committed the foul wants it enforced and the team that was fouled does not.
The same reasoning covers the plain version with no hard count. A punting team that reaches fourth down around midfield with a running clock and no reason to hurry will sometimes let the clock expire for the room alone. The choice between punting and going for it there is a larger argument, laid out in our piece on fourth-down analytics.
Where the five yards are marked off: succeeding spot, previous spot and half the distance
The penalty line under Article 5 gives two enforcement spots and people tend to remember one.
Loss of five yards from the succeeding spot, if the foul occurs between downs and the ball remains dead. That is the play-clock delay, the spike and nearly everything else. The succeeding spot is where the ball would next have been snapped, so the yards come straight off the line of scrimmage.
Loss of five yards from the previous spot, if the ball was in play. This covers the unusual case in which a delaying act is ruled to have happened during a live down. It is rare, and most fans will go seasons without seeing it enforced that way.
The down and the line to gain
The down is replayed, or more exactly it is never played. What changes is the distance, and here the timing of the foul matters more than fans expect.
| When the delay happened | Result after five yards |
|---|---|
| Play clock expires on second-and-6 | Second-and-11 |
| Play clock expires on the first snap of a new series | First-and-15 |
| Offense spikes the ball right after gaining a first down | First-and-10 from five yards back |
| Defense delays on third-and-4 | First down, because the yardage reaches the line to gain |
| Defense delays on third-and-9 | Third-and-4 |
Half the distance, and what cannot be stacked
Near a goal line no penalty may carry the ball more than halfway to it. An offense that lets the clock expire at its own 3-yard line is moved to roughly the 1½. A defense flagged at its own 6 gives up three yards.
Delay is also a foul that does not combine with what follows. Because the ball never became live, there is no play for a second foul to attach to. If the defense then jumps on the replayed down, that is a new foul on a new snap, and the two five-yard walks cancel on the field without ever having offset in the rulebook's sense.
Delay as clock strategy: New England, Tennessee and the rules that answered them
On October 21, 2019, New England led the New York Jets 33-0 in the fourth quarter at MetLife Stadium and lined up to punt. The Patriots let the play clock expire, committed a second dead-ball foul on the replayed down, and only then punted.
The loophole worked like this. Outside the final five minutes of the game, a dead-ball foul stopped the clock only until the penalty was marked off. The referee then wound it and the play clock started again. So a team with a lead and a running clock could let 40 seconds expire, take five yards, let another 25 run, take five more, and only then kick. Ten yards of field position bought more than a minute.
It came back on Bill Belichick less than three months later. In the wild-card game at Gillette Stadium on January 4, 2020, Tennessee led New England 14-13 in the fourth quarter and sent out its punt team. Mike Vrabel, who had played linebacker for him, had his players take deliberate pre-snap fouls before the kick, and the clock ran between each of them without a snap that counted. Tennessee won 20-13.
What the rulebook says now
The league rewrote the timing rules for the 2020 season to stop teams from manipulating the game clock with multiple dead-ball fouls. The current book does it in three places.
First, if the offense commits a foul during the fourth quarter after the ball is ready for play and the foul stops the clock before a snap, the game clock stays stopped until the next snap. The first deliberate delay still burns its 40 seconds, which a team could have burned legally by snapping at one. It buys nothing more.
Second, two successive delay-of-game penalties by the offense on the same down with the clock running are unsportsmanlike conduct. Fifteen yards, and the clock starts on the snap.
Third, a general prohibition: a team may not commit multiple fouls during the same down in an attempt to manipulate the game clock. The penalty is 15 yards, and the game clock is reset to where it stood at the snap.
The interplay between the two clocks, and when each restarts after a stoppage, is the subject of our guide to NFL game clock rules.
Why a delay-of-game call, or the lack of one, cannot be challenged
Baltimore's late snap in Detroit looked like the most reviewable thing imaginable. There is a clock. It shows a number. A camera can freeze the frame.
It is not reviewable, and the reason is structural. Rule 15 of the rulebook lists the rulings that replay may examine, and ends its list of exclusions with a catch-all: any aspect of a play not listed as reviewable is not reviewable. Whether the play clock expired before the snap is not on the list, and a head coach cannot throw the red flag for it in either direction. A delay that was called wrongly stands just as firmly as one that was missed.
What the crew can do without replay is correct a play clock that was started wrongly or interrupted. The referee stops everything and pumps one arm overhead to have the operator reset it to 25 seconds, or two arms for 40. That fixes the next snap. It does nothing about the last one.
The game clock gets limited treatment that the play clock does not. Replay can restore time that ran off in error, and can determine whether a period expired before a snap. That is the game clock, the one that decides when halves end. The play clock is treated as an administrative timer run by an operator on officials' signals, and its expiry as a judgment the back judge makes with his eyes. The full list of what replay can and cannot fix is in our explainer on the NFL's challenge and replay rules.
There are arguments for leaving it alone. A play-clock review would need the stadium clock and the broadcast picture synchronized to a standard nobody currently certifies. It would invite a challenge on any snap that was close, and close snaps are an offense's deliberate habit when it is protecting a lead. And the mechanic's built-in lag would have to be written down as a number, at which point offenses would snap at that number instead of at zero.
The argument on the other side is the Tucker kick. A league that reviews whether a toe was on a sideline will not look at a zero on a clock before a game-winning field goal, and that is hard to defend to the team that lost.
Timeout or flag: the sideline's choice as the play clock dies
With four seconds on the play clock and the offense still shifting, somebody has to decide. The quarterback can signal for a timeout. The head coach can ask the nearest official for one. Or everybody can let it go and accept the flag.
The price list is not fixed. It depends on the down, the distance, the score and how many timeouts are left.
| Situation | What five yards cost | Usual choice |
|---|---|---|
| First-and-10 in the first quarter | Little; three downs remain to recover it | Take the flag |
| Third-and-1 anywhere | A great deal; the playbook shrinks to passes | Timeout |
| Fourth-and-goal from the 1 | Often the touchdown attempt itself | Timeout |
| Punt formation near midfield | Nothing, or a small gain for the punter | Take the flag |
| Trailing late in the second half | Five yards and, with the clock running, possibly ten seconds | Depends on timeouts left |
A timeout has no yardage attached, and its value is almost entirely in the last few minutes of each half, when it is the only tool that stops a running clock on demand. A coach who burns one in the first quarter to save five yards on first down has made a bad trade, and most coaches know it. The ones who burn it anyway are usually reacting to the look of the thing. A delay of game reads as disorganization, and no play-caller enjoys it.
The request that arrives at zero
A timeout has to be requested before the foul. Officials on the wing are listening for the coach's voice and watching the quarterback's hands as the clock winds down, and when the request and the zero arrive together the crew has to rule on which came first.
The defense can spend a timeout here as well, for a different reason. A defense that has been caught with the wrong personnel, or with 12 men about to be on the field, sometimes calls time as the offense's play clock is about to expire, and in doing so rescues the offense from a delay it was about to take.
How the foul differs in college and high school football
The play-clock foul itself is nearly identical at every level in the United States. College football under the NCAA rulebook and high school football under the National Federation rules both use a 40-second clock after an ordinary play and a 25-second clock after administrative stoppages, and both charge five yards when it runs out. The differences are in the acts around it.
The spike. This is the one that catches players moving between levels. In the NFL, spiking the ball after a non-scoring play is a five-yard delay. The NCAA book treats throwing or spiking the ball away after a play as unsportsmanlike conduct when it is done to draw attention, a 15-yard foul, and two unsportsmanlike fouls by one player in a game mean ejection. A habit that is cheap on Sunday can be expensive on Saturday.
Deliberate fouls for clock. College football had its own version of the 2019 lesson. On October 12, 2024, Oregon sent a twelfth defender onto the field in the final seconds against Ohio State, took the five-yard penalty and let the final seconds run off on a play the Buckeyes could not get back. Oregon won 32-31. Within days the NCAA's rules committee changed the rule so that, after such a foul late in a half, the offense can have the game clock reset to where it stood at the snap. The foul was illegal substitution, not delay, but the principle is the one the NFL adopted in 2020: a team should not be able to buy time with a penalty.
The runoff. The NFL's ten-second runoff applies after the two-minute warning. College football has a comparable ten-second subtraction for clock-stopping fouls late in a half. High school rules take a different approach late in a half and give the offended team a say in when the clock restarts.
Who watches the clock. The back judge has it in the NFL and in a full college crew. High school games are frequently worked with five officials, sometimes with no visible play clock at the field, in which case the count is kept by an official on the field.
Other points at which the Saturday and Sunday rulebooks diverge are collected in our guide to college football and NFL rule differences, and the rest of the site's coverage of the sport is on our American football page.
The NFL's version of the rule is, on the whole, lenient toward honest lateness and hard on calculation. A team that simply runs out of time loses five yards and plays the down again. A team that uses the rule as a tool, to bleed a clock or bait a lineman or freeze a hurry-up offense, now meets a 15-yard answer, a runoff or a clock that refuses to move.
