A clean catch by a player will enable a retired player for that team to return to the court. In order for a catch to be clean:

• it must not have touched any player, ball, object, person or surface before the catching player has full possession, except:

• the ball may touch the player attempting the catch, prior to the catch being made, provided that no other player, ball, object, person or surface is touched between the initial touch and the catch
  

• when a player already has possession of a ball and catches a second ball without dropping the other ball first; if the first ball is touched by the second ball after it has touched the player, the original ball will be considered as part of the player while he/she is in the process of catching the second ball
  

• the player must have full possession of the ball in their hand(s) with some part of their body touching the court within their team’s boundary lines.
  
• the catch must be completed before any any part of a player’s body touches down out of bounds.
