Interference takes place when a player obstructs, blocks, screens or charges towards an opponent, with or without direct contact, in such a manner that prevents the opponent's approach to the ball carrier, potential ball carrier or the ball. Blocking is identified as the act of creating interference with contact.
On any play from scrimmage, a Team B player may use hands and arms to reach the ball carrier, but shall not hold or encircle any Team A player, other than the ball carrier.
No player of either team may thrust his hands forward above the frame to contact the opponent on the neck, face, head or facemask. This does not apply to a ball carrier using a "stiff arm" or "straight arm" tactic where there is no grasping of the face mask.
