SO I was reviewing the overtime procedures and came across this: Pg 83, 5-1-1 "if the defensive team gains possession, the ball becomes dead immediately and the offensive team's series of downs is ended. "
Then on pg 84, 8-1 "If the defensive team scores a safety or touchdown, the game is ended."
If B intercepts a pass or scoops up a fumble and takes it back for an apparent touchdown we are to kill the play when B gains possession of does the score count?
