If a ball carrier falls to the ground, and the other team wishes to run the clock because they are leading, how many seconds will the umps allow the clock to run?
If a ball carrier falls to the ground, how many seconds will the umps allow the clock to run?
The referees will let the play run until they determine that the ball carrier is making no immediate effort to advance. At this point, the play is blown dead, and the clock will continue to run until an event that stops the clock takes place (eg, timeout, delay of game, the result of the following play stops the clock).
Rule 7, Section 2, Article 1-d-1 states:
An official shall declare the ball dead and the down ended:
when a runner declares himself down by:
falling to the ground, or kneeling, and clearly making no immediate effort to advance.
Up to 40 seconds.
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.
once the play is over the refs will stop the clock asap if there is a reason to such as a timeout or an incomplete pass (if they don't do so on time they will likely ask for the clock to be reset to the correct position), otherwise the clock won't stop at all they just keep going (and the offense has 40 seconds to start the next play).
