untimed down?
 

with 4 seconds remaining in the 1st quarter team A has a dead ball false start penalty. team B accepts the penalty. the referee winds the clock and the clock runs out before team A can snap the ball. do we have an untimed down?

I would say no since this was not during the last time down.

ART. 3 . . . A period must be extended by an untimed down if during the last timed down of the period, one of the following occurred:

a. There was a foul by either team and the penalty is accepted, except for those fouls listed in 3-3-4b.

b. There was a double foul.

c. There was an inadvertent whistle.

d. If a touchdown was scored, the try is attempted unless the touchdown is scored during the last down of the fourth period and the point(s) would not affect the outcome of the game or playoff qualifying.

If (a), (b), (c) or (d) occurs during the untimed down, the procedure is repeated.

NFHS, no untamed down. If its the 4th Q, I probably tell A the clock will run.

4 seconds is plenty of time to snap the ball when your play has already been called.

thanks for that fine answer but thats not the question. i am talking about a rule.

The answer's in the first reply. The penalty didn't happen during the last timed down of the period, therefore you don't extend the period.

I didn't feel the need to repeat the answer, so I commented on why I felt the rule is appropriate.

The purpose of the rule is to keep a team who's behind at the end of the half/game from intentionally fouling to gain an advantage.

I say yes. Live ball accepted foul end of quarter, there is always an untimed down, even if there are a few seconds left on the clock, and it runs out.
nfhs case book, rule 3, 3.3.3B

The OP had a false start as the penalty. That's a dead ball foul.

Oops..I missed that part! sorry
