(Note 4) Slew Footing is the act of a player using his leg or foot to knock or kick an opponent's feet from under him. This is done by pushing an opponent's upper body backwards with an arm or elbow at the same time using a forward motion of his leg causing the opponent to fall to the ice.
(a) A minor or major penalty shall be assessed under this rule for any of the actions described above.
