Substitution is unlimited, but permitted only when the ball is not in play. To begin the game, a coin toss will determine the right to possession or pass possession to the opposing team. If the game goes into overtime, the team not receiving possession to start the regulation game shall receive the ball to start overtime. The team winning the toss shall have the right to accept or refuse the ball. If they refuse the ball, they shall receive first possession in the overtime period.
Jump balls go to the defense.
On all double fouls, the ball shall remain with the offense. Failure to take it back will result in the loss of possession and the loss of any points resulting from that possession. It is not a violation unless a shot is attempted prior to taking the ball behind the 20-foot arc. If a shot is attempted prior to the ball being taken back and you are fouled, the foul does not count and the ball changes possession. The defensive player must check the ball before it is put into play.
