Rule 4
Section 34. Goaltending
Art. 1. Goaltending shall have occurred when a defensive player touches the ball during a field-goal try and each of the following conditions is met:
Exceptions: Rules 10-3.6; 10-6.1.i
a. The ball is in its downward flight; and
b. The entire ball is above the level of the ring and has the possibility, while in flight, of entering the basket and is not touching the cylinder.

Art. 3. When the entire ball is above the level of the ring during a field-goal try and contacts the backboard, it is considered to be on its downward flight. In such a case, it is goaltending when the ball is touched by a player.
