Box Lacrosse Rules Explained: The NLL Fan's Beginner Guide

National Lacrosse League box lacrosse is a fast, physical indoor version of lacrosse played with six players per team on the floor, a 30-second shot clock and four 15-minute quarters. The six players normally consist of five runners and one goalkeeper.

Unlike field lacrosse, NLL games are played on an enclosed artificial surface surrounded by boards and glass. The boards generally keep the ball in play, substitutions happen rapidly and certain forms of cross-checking are legal. For new fans, understanding the shot clock, boards, substitutions, contact and crease rules explains much of what happens during an NLL game.

What Are The Basic Rules Of NLL Box Lacrosse?

NLL box lacrosse is played six-on-six, with five runners and one goalkeeper normally on the floor for each team. Regulation lasts 60 minutes, divided into four 15-minute quarters.

The objective is to put the ball completely across the goal plane between the posts and under the crossbar. NLL goals measure 4 feet, 9 inches wide by 4 feet high, smaller than the 6-by-6-foot goals used in NCAA field lacrosse.

NLL teams can remove their goalkeeper for another runner, but the replacement runner does not receive goalkeeper privileges.

How Does The 30-Second Shot Clock Work In The NLL?

The NLL uses a 30-second shot clock that limits how long a team can possess the ball without producing a qualifying shot. The shot clock begins with team possession and operates during regulation and overtime.

Qualifying shots can reset the clock, including shots that hit the goal, goalpost or a properly positioned goalkeeper under NLL rules.

The short clock helps explain the game's pace. Teams cannot simply maintain possession for long stretches. They must quickly create a scoring opportunity or risk losing the ball.

Are The Boards Live In Box Lacrosse?

Yes, the boards generally are live in NLL box lacrosse. A pass or shot that hits the boards can rebound back onto the floor and remain in play.

That creates a major difference from field lacrosse. A missed pass does not necessarily result in an out-of-bounds restart, and players can continue pursuing balls that ricochet around the enclosed playing surface.

The ball still can go out of bounds if it contacts something or someone outside the defined playing surface under NLL rules.

How Do Substitutions Work In NLL Lacrosse?

NLL teams can substitute players on the fly while play continues. Players enter and leave through the designated bench and change area, allowing teams to make frequent changes throughout a game.

That can resemble hockey-style line changes for a new viewer. Teams frequently swap groups of runners as possession changes rather than waiting for every substitution to occur during a stoppage.

Illegal substitutions can result in penalties, including situations involving too many players on the floor.

Is Cross-Checking Legal In The NLL?

Certain forms of cross-checking are legal in the NLL, but cross-checking is not universally legal. A cross-check is contact made using the stick shaft between a player's hands.

Under NLL rules, a player can legally cross-check an opponent who has possession on the arms, below the shoulders and above the waist while using both hands on the stick.

Contact above the shoulders, below the waist or from behind is illegal. Excessive or otherwise illegal cross-checking also can result in penalties of varying severity.

These are specifically NLL rules. Other versions of box lacrosse can use different rules for contact and cross-checking.     Lacrosse Evergreen Article Rese…

What Is The Crease Rule In NLL Lacrosse?

The crease is the protected area around the NLL goal, and attackers face restrictions on entering it. A player carrying the ball commits a crease violation if any part of the player's body is on or inside the crease, although the stick may extend into it.

A shooter's momentum can carry the player through the crease after releasing the ball in certain circumstances. However, if prohibited crease contact occurs before the ball completely crosses the goal plane, the goal is disallowed.

A goalkeeper or defender possessing the ball in the crease also must move it out within four seconds.

How Do Penalties Work In NLL Lacrosse?

NLL penalties can result in anything from a change of possession to a player serving time in the penalty box. A time-serving penalty can create an extra-man opportunity for the opposing team.

A minor penalty normally lasts two minutes, while a major lasts five minutes. A misconduct lasts 10 minutes, though a substitute ordinarily replaces the player serving a misconduct, meaning the team is not necessarily shorthanded for those 10 minutes.

A standard minor also can end early when the opposing team scores an applicable extra-man goal. Major penalties are administered differently.

Is Fighting Legal In The NLL?

No. Fighting is penalized under NLL rules. The physical nature of box lacrosse does not mean players are permitted to fight without consequences.

NLL rules distinguish fighting from other rough play. Fighting can result in a major penalty, while an instigator or aggressor can receive additional penalties and a game misconduct. Repeat incidents also can lead to suspensions.     Lacrosse Evergreen Article Rese…

How Does Overtime Work In The NLL?

NLL games tied after regulation use repeating 15-minute sudden-death overtime periods. The first team to score wins the game.

The 30-second shot clock remains in use during overtime.

What Should A New NLL Fan Watch For?

New NLL fans should start by watching the 30-second shot clock, live boards, rapid substitutions, crease and physical play. Those rules explain much of the speed and flow that distinguishes NLL box lacrosse.

Watch how quickly teams attack after gaining possession, how runners change as the ball moves from one end to the other and how rebounds off the boards keep plays alive.

Near the goal, pay attention to the crease and the timing of a shooter's movement through it. When a penalty is called, look for the resulting extra-man opportunity.

Once those concepts become familiar, the action in an NLL game becomes considerably easier to follow.
