NFL (2011-2012)

Rule 7
Section 4, Article 2

Item 4: Player Under Center. It is legal for a player who has taken a position under or behind the center to go in motion, whether he has placed his hands under center, on his knees, or on the body of the center. However, it is a false start if the action is quick and abrupt, or if the player fails to come to a complete stop prior to the ball being snapped.
