• Basket interference occurs when a player:
  • Touches the ball or any part of the basket (including the net) while the ball is on or within the imaginary cylinder above the rim.
• Key points for officials:
  • Accidental contact with the net that does not affect the ball should not be called basket interference.
  • If a defender’s hand is legally in contact with the ball during a dunk attempt, it is not basket interference.
  • Reaching up through the basket from below and touching the ball is basket interference.
  • Pulling down the rim so it contacts the ball before returning to its normal position and causing it to take an unnatural bounce is basket interference.
