SEC spokesman Charles Bloom:
"The foul for taking helmet off is a live ball foul treated as a dead-ball foul," Bloom wrote in an e-mail Saturday night. "That is, if it happens on a play where time does not expire then the penalty is enforced on the following play. However since the clock ran out on that play, then there is no next play, so there is no penalty to mark off."
Blown call doesn't matter as Alabama edges Tennessee
