3-3-2 . . . The substitute shall remain outside the boundary until an official beckons, whereupon he/she shall enter immediately. If the ball is about to become live, the beckoning signal should be withheld. The entering substitute shall not replace a designated jumper or a free thrower except as in 8-2 and 3. If the substitute enters to replace a player who must jump or attempt a free throw, he/she shall withdraw until the next opportunity to substitute.

Learned something today............. good question
