Defensive Foul in the post, dislodging, defender uses knee

This is an example of a defensive foul for dislodging. A post defender may not dislodge, reroute or impede an offensive player. A defender may legally position his leg between the legs of an offensive player in the lower defensive box to maintain his position. However, once the defender’s foot is lifted off the floor, dislodging his opponent, a foul shall be assessed. On this play, the post defender uses his knee to dislodge his opponent.
