On a rebound situation, Red 21 gets the ball and tries to dunk it. In his motion, the ball leaves his hands. Then Red 21 grabs the ring and the ball finally enters the basket. The referee cancels the basket. Article 31.2.4 Interference occurs when: A player causes the basket to vibrate or grasps the basket in such a way that, in the judgement of a referee, the ball has been prevented from entering the basket or has been caused to enter the basket. Outcome: Correct decision from the referees. Red 21 committed an offensive interference as he grasped the basket and, in the judgement of the referee, this has caused the ball to enter the basket. The basket is not valid, and the game will be resumed with a White team throw-in from the throw-in line extended and 24 seconds on the shot clock.
