Untimed down?

[cowbyfan1]

But an encroachment is a dead ball foul and not during the last TIMED down. In this case it was not a timed down as the down would begin with the snap. Fed in rule 3-3-3 highlights timed.
They also point out that if time ran out during a sucessful field goal or if it was out during a try, and the kicking teams accepts a suceeding spot enforcement, then the period is not extended.
