Changes to Rule 7-1-6 expand on the situations required for encroachment to occur after the ready-for-play and after the snapper has placed his hand(s) on the ball. The rule previously stated that encroachment occurred if “any other player breaks the plane of the neutral zone.” In addition, now defensive players are restricted from contacting the ball prior to the end of the snap or making contact with the snapper’s hand(s) or arm(s) until the snapper has released the ball.
