Carroll led, 21-14, in regulation and stopped Allen on fourth-and-goal from the 5 with 1:33 to play. But the Dragons couldn't run out the clock and had to punt in the final seconds.
On fourth down from the 11, Carroll's snap to the punter was high and bobbled. The punt appeared to be partially blocked and only went 16 yards. The video starts with Allen getting the ball back with 1 second left.
