This is an example of a free throw violation committed by a defensive player positioned along the lane line. During free throw attempts, defensive players positioned along the lane lines may not enter the key nor vacate their lane space by more than three feet, until the ball is released by the shooter. On this play, the highlighted defensive player exceeds the allowed distance as he vacates his position on the lane line prior to the release of the ball, causing a violation to be assessed when the shot is unsuccessful.
