National Lacrosse League (NLL)

Season and structure

NLL seasons typically begin in late winter and run into the spring. Teams play a regular season schedule followed by a postseason tournament to determine the league champion. A standard regular season schedule has historically included around eighteen games per club, though exact lengths and formats have varied by year. Broad details and the current schedule are published by the league and in team media guides; consult official schedules for specifics.

Gameplay characteristics

Box lacrosse differs from outdoor field lacrosse in several key ways: it is played indoors on a surface surrounded by dasher boards; rosters and on‑floor numbers are smaller; and a shot clock is used to keep the tempo high. Teams substitute frequently, and the presence of boards produces unique strategies such as bank passes and rebound plays. Rules and equipment specifics are available through rulebooks and coaching materials; see rules and resources for more.

History and development

The league traces its roots to professional indoor lacrosse efforts of the late 20th century and has evolved through name changes, expansion, contraction and franchise relocation. Over decades the NLL has worked to stabilize schedules, grow attendance, and increase televisual and streaming exposure. The league’s cross‑border composition—featuring clubs in both the United States and Canada—reflects lacrosse’s strong roots and popularity in both countries.

Organization, teams and competition

• Clubs operate as professional franchises in arenas shared with other sports and events.
• Playoffs determine the champion after the regular season, often culminating in a single championship game or series.
• Rules on roster composition, player acquisition, and salary matters are set by the league and its teams.

Because the NLL balances North American markets, team locations and the number of franchises have changed over time. Current team pages and franchise histories are maintained by the league and by team organizations; see team information for details.

Significance and distinctions

The NLL plays a major role in the professionalization of lacrosse, offering a year‑round career path for players who also participate in field lacrosse at other times. Its indoor format produces a distinctive spectator experience: smaller playing surface, higher scoring rates, and continuous action aided by the shot clock and boards. The league serves as a development and showcase platform for players, coaches, and officials, and contributes to the sport’s visibility through regional rivalries and championship events.
