A trails 7-0 with :01 left. A on B5 4th and goal.
Play: A1 throws to end zone. B1 commits defensive pass interference in end zone, but intercepts the ball, runs out of the endzone and scores. During the return, coach A berates the officials and gets a flag for unsportsmanlike conduct.
Is the game over if Team B accepts the unsportsmanlike on the head coach?
According to 3-3-4b. A period shall not be extended by an untimed down if there was a foul by either team and the penalty is accepted for a non-player foul.
