Southern Box Lacrosse follows the FIL rules and regulations. Where appropriate and necessary, the FIL Rules may be adapted to fit the mission, goals, and objectives of the SBL league, players, coaches and referees.
Indoor lacrosse combines the physical play of ice hockey with the high scoring, fast pace and play-making style of basketball. Indoor lacrosse is played inside the confines of a rink, with glass and rink boards intact known as the Box. The playing surfaces normally consists of a roller hockey tiled surface suitable for the fast-paced, up-and-down style of play.
Each team has five runners (forwards and defenseman) and a goaltender on the floor during the game. Each team can dress a maximum of sixteen players (fifteen runners and one goaltender) per game, and the players rotate on and off the floor in shifts, similar to ice hockey. The game consists of four quarters, each twelve minutes in length. A game that is tied at the end of regulation is decided in a sudden-death overtime. There are no tie games in indoor lacrosse.
