The National Lacrosse League is North America's professional indoor lacrosse league, featuring the best lacrosse players in the world. The NLL has nine teams playing in the major markets of the United States and Canada. NLL teams each play a 16-game regular season schedule (eight home and eight away) that begins in December and runs through April, followed by the Champion's Cup Playoffs. All games are played on the weekends. Professional indoor lacrosse combines the physical play of hockey with the high scoring, fast pace and play-making style of basketball. Indoor lacrosse is played inside the confines of an ice hockey rink, with glass and rink boards intact. The playing surface consists of a green dieter turf carpet that is laid down over the hockey ice. The two teams combine to score a total of 25 goals in the average NLL game.

Each team has five runners (forwards and defenseman) and a goaltender on the floor during the game. Each team dresses eighteen players (sixteen runners and two goaltenders) per game, and the players rotate on and off the floor in shifts, similar to ice hockey. The game consists of four quarters, each fifteen 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 professional indoor lacrosse.
