The Box Lacrosse Rules You Need Before Playing

Get the box lacrosse rules for player numbers, shot-clock resets, substitutions, legal contact, crease violations and penalties under World Lacrosse rules.

Cody Bearpaw · 5 min read

Box lacrosse normally uses five runners and one goalkeeper per team, with 10 seconds to advance from the defensive half and 30 seconds to take a shot on goal. Live substitutions and regulated contact are allowed, but illegal changes, checks and crease entries can cost possession or bring penalties. These are the box lacrosse rules under the World Lacrosse baseline—not the rules for field lacrosse or Sixes.

Choose what happened to the shot; check whether the shot clock resets.

Shot-Clock Reset Check

Reset To 30 Seconds

A deflection off the goalkeeper while the goalkeeper is in the crease resets the shot clock.

This guide uses the World Lacrosse 2026–2028 rules, May 2026 version 2.0. Those govern World Lacrosse competitions, qualification events and specified international games. National bodies may adapt them or choose their own implementation timeline, so check your league’s rulebook and age-group modifications before playing. World Lacrosse rulebook, authority and implementation.

Five Runners And A Goalkeeper Play At Full Strength

A runner is a non-goalkeeper player. Teams play inside a boarded enclosure and score by sending the ball completely across the goal line from the front, between the posts and beneath the crossbar. A goalkeeper can be replaced by an extra runner, leaving the net unattended.

Regulation is four 15-minute quarters, with the game clock stopped during dead-ball situations. Center face-offs start quarters and overtime periods and restart play after goals. World Lacrosse, rules 1.1, 3.1–3.2, 5.1–5.3, 6.2 and 6.11.

Advance Within 10 Seconds, Then Protect The Centerline

When your team gains possession in its defensive half, it has 10 seconds to get the ball across the centerline. If you carry it across, both feet must reach the offensive half without touching the line; a loose ball crossing also satisfies the requirement.

Once offensive-half possession is established, you generally cannot send the ball back across—or onto—the centerline. Exceptions include shots on goal and the defensive team being last to touch the ball. World Lacrosse, rules 6.4–6.5.

After a defensive recovery, look for a forward outlet. Once across halfway, avoid drifting back onto the line while protecting your stick. Crossing halfway solves the advance requirement; it does not give you permission to retreat freely.

The 30-Second Clock Requires A Shot On Goal

The team in possession has 30 seconds to take a shot on goal. A violation gives possession to the opponent. Shooting wide into the end boards does not satisfy the requirement or earn a fresh clock.

Ball Contact Shot-Clock Reset
Goalkeeper deflection, goalkeeper in crease Yes
Goalpost Yes
Boards only on a wide shot No
Defender’s touch without possession Normally no
Runner in crease, goalkeeper pulled Yes, on a deflection

The runner-in-the-crease exception applies when the goalkeeper has been pulled for an extra attacker. It does not mean every defensive deflection resets the clock. World Lacrosse, rule 6.6.

Check the clock when you receive the ball. After a rebound, confirm the reset rather than assuming you have another 30 seconds.

Live Substitutions Depend On The Outgoing Player’s Position

Box allows substitutions during live play. The incoming player waits until the player being replaced has both feet inside the marked substitution area. The outgoing player has right-of-way and must leave the floor for the bench. Illegal substitution brings a bench minor penalty. World Lacrosse, rule 6.13.

Identify the player you are replacing before entering. Follow the bench call, not simply the sight of someone running toward you: a teammate approaching the bench is not yet permission to step onto the floor.

Legal Contact Has A Defined Target And Direction

“Box allows cross-checking” does not mean any shaft contact is legal. World Lacrosse defines a legal cross-check as a two-handed check to a ball carrier’s arms, below the shoulders and above the waist. Cross-checks to the back, above the shoulders or below the waist are illegal; off-ball contact has additional restrictions.

Body checks on a ball carrier may be legal from the front or side, below the shoulders and above the waist, subject to the rules protecting vulnerable players. Cross-checks and body checks must not contact the head or neck, including on the follow-through.

Boarding—checking someone so they are thrown violently into the boards—and checking from behind are separately penalized. The presence of boards does not make driving an opponent into them legal. World Lacrosse, rules 8.4 and 8.11–8.15.

Picks, which impede a defender’s coverage, are part of the game. But grabbing, forceful body contact and excessive cross-checking during a pick are not permitted. World Lacrosse, rule 8.2.

Learn contact with proper equipment and coaching. For recreational play, confirm whether your competition is non-contact box rather than assuming the contact rules above apply.

The Crease Line Counts As Part Of The Crease

The crease is the marked area around the goal. An attacker carrying the ball commits a crease violation if any body part touches its line or the area inside it. Stick-only contact with the crease is not itself a violation.

A shooter making body contact with the crease before the ball completely crosses the goal line normally loses the goal. There are exceptions when an illegal defensive check forces the attacker into the crease.

At the other end, a goalkeeper or defender gaining control in the crease has four seconds to pass or leave it. A player cannot enter their own crease carrying the ball. A goalkeeper or defender in the crease also cannot touch a ball deliberately directed back there by a teammate, unless an opponent deflects it. World Lacrosse, rules 8.8–8.10.

For an attacker, watch your feet as well as your stick near goal. For a defender, the crease is not a place to carry the ball for protection or receive a deliberate return pass.

Violations Can Change Possession Or Player Numbers

Technical violations generally cost possession. Penalties can also leave a team short-handed.

Penalty Duration
Minor Two minutes
Major Five minutes

A power play is the numerical advantage created when the opponent is short-handed. In the straightforward case of one minor penalty, a goal by the advantaged team ends that penalty early. Coincidental penalties and majors work differently; do not assume every power-play goal releases a penalized player. World Lacrosse, rules 7.1–7.3.

If the ball leaves the enclosure, possession normally goes to the team that did not touch it last. One exception: a shot deflecting directly off a goalpost and out remains with the offense. World Lacrosse, rule 6.7.

Before your first practice, ask the coach to walk through one defensive recovery, advance, shot and line change. Locate the centerline, shot clock, crease boundary and substitution area first: those are the reference points you need while the ball is moving.
