Jr. B Basketball Rules at a Glance Each half is 16 minutes running time, with the last two minutes of each half played stop time. There are five time outs during regulation play and one per overtime period. There is a three-minute half time. Pressing by any team is not allowed. Man-to-man half-court defence is allowed. No zone defence is allowed at anytime. Referees give a 10-second warning to any team they feel is delaying the game. In held-ball situations, teams alternate taking possession of the ball at the designated spot nearest to where the held ball occured. The home team has choice of bench, while visiting team has choice of basket. Once control of the ball is established off the backboard, defence must vacate to half court. Substitutions occur freely on dead balls (as per ASAA rules). Coaches attempt to provide players with equal playing time, with no athlete playing more than eight minutes per half. The host school clearly marks the foul line (with tape) three feet closer to the basket. Players may shoot from any position they wish behind that line. Basket height is the standard 10 feet. Referees may reduce warm-up and/or half time to run the tournament on schedule. The bonus penalty is shot when a team reaches seven team fouls in one half. On an over-and-back call, possession is taken in the front court only. The ball is in-bounded from the nearest end or side line. There is no handle in the back court. Four opponents of the free-thrower and two teammates of the free-thrower are permitted on the free throw lane. All other players are to be behind the free-throw line.
