Team A has a designated spot throw-in along the end line. Thrower A1 extends the ball with his/her arms over the end line such that part of the forearms, hands and the ball are entirely on the inbounds side of the boundary line. B2 slaps A1 on the wrist and dislodges the ball.
When a defender makes contact with a thrower-in, the result is an intentional foul. Where A1’s arms are located (on the inbounds or out-of-bounds side of the boundary line) is immaterial for this penalty to be assessed. A1 is awarded two free throws and Team A awarded a throw-in at the spot nearest the foul. COMMENT: For a boundary plane violation warning to also be assessed, the defender must actually violate the rule and penetrate the boundary plane.
