Elam briefly touched his visor, but here is the rulebook (Elam did not grasp and twist, pull, etc., therefore phantom call):
ARTICLE 15. TWISTING, PULLING, OR TURNING THE FACEMASK OR HELMET OPENING. No player shall grasp and
control, twist, turn, push, or pull the facemask or helmet opening of an opponent in any direction.
Note: If a player grasps an opponent’s facemask or helmet opening, he must immediately release it. If he does not
immediately release it and controls his opponent, it is a foul.
Penalty: For twisting, turning, pushing, pulling, or controlling the mask or helmet opening: Loss of 15 yards. The player
may be disqualified if the action is flagrant. If the foul is by the defense, it is also an automatic first down.
