How do NFL 10-second runoffs differ for offensive fouls and replay corrections?
After either half’s two-minute warning, a listed time-conserving act by the offense while the game clock is running can cause a 10-second runoff. A separate runoff can follow a qualifying replay reversal or nullified foul when the correct ruling would leave the clock running or restart it before the next snap. The triggers and timeout or decline choices differ.
For NFL viewers asking why time can disappear after an offensive foul near halftime or the end of a game. · Updated
The offensive runoff follows listed time-conserving acts
Rule 4-7-1 applies after the two-minute warning of either half. Its list includes a clock-stopping foul during a dead-ball period, intentional grounding, an illegal forward pass, throwing a backward pass out of bounds, spiking or throwing the ball after a down ends except after a touchdown, and illegally batting or kicking the ball out of bounds. When the offense commits a listed act while time is in, the rule runs 10 seconds and resets the play clock to 30. Rule 4-7-2 also provides a 10-second runoff for a dead-ball substitution violation after the warning while time is in.
For this branch, the offense may use an available timeout instead of the runoff. The defense may decline the 10 seconds and accept the yardage penalty. If the yardage penalty is declined, the runoff is also declined, the play clock is set to 25 seconds, and the clock starts on the snap.
- The offensive runoff applies to listed acts after a two-minute warning while time is in.
- An available offensive timeout can replace it.
- The defense may decline the runoff while accepting yardage; declining the yardage also declines the runoff.
A replay correction has a different trigger and different choices
After a two-minute warning, Rule 4-7-4 covers a replay reversal or a foul called while time is in and later nullified. The 10-second runoff applies when the correct ruling would not have stopped the game clock or would have restarted it before the next snap. The play clock is set to 30 seconds, and both clocks start on the ready-for-play signal.
Neither team may decline this replay-related runoff. Either team can prevent it with a remaining timeout. If a timeout prevents it, the game clock is reset to when the play should have ended, the play clock is set to 25 seconds, and the game clock starts on the snap. Rule 15-5-2 says that if fewer than 10 seconds remain after the reset, the half or game is over.
- Offensive time-conservation branch: the offense may use a timeout, and the defense has the stated penalty choices.
- Replay branch: neither team may decline; either may use a remaining timeout to prevent the runoff.
The shared 10-second amount does not make the rules interchangeable
The two rules can produce the same clock loss, but they do not share one trigger or one set of choices. Identify whether the time change comes from a listed offensive act or a replay correction, then use only that branch’s conditions. A time-conservation runoff is not automatic after every offensive foul, and the defense’s penalty choice does not carry over to replay.
Two fictional late-game branches
In one fictional second quarter, 1:40 remains after the two-minute warning and the game clock is running when the offense intentionally grounds a pass. The listed act produces a 10-second runoff; the offense may use an available timeout instead. The defense may decline the runoff while accepting yardage, and if it declines the yardage the runoff is declined too. In a separate fictional fourth quarter, replay after the warning reverses a ruling and the correct ruling would have left the game clock running. Neither team can decline that branch’s 10-second runoff, though either can prevent it with a remaining timeout.
Related questions
Does every offensive foul cause a 10-second runoff?
No. Rule 4-7-1 lists time-conserving acts and applies its offensive runoff after a two-minute warning when time is in. Other clock stoppages follow their own rules.
Can the defense decline both the yardage penalty and the offensive runoff?
If the defense declines the yardage penalty in the offensive time-conservation branch, the 10-second runoff is also declined. That choice does not apply to the separate replay-related runoff.
Can a team prevent a replay-related 10-second runoff?
Yes. Neither team may decline that runoff, but either team may prevent it by taking a remaining charged timeout.
