Lacrosse Overtime Rules: What Changes Between Box, Field and Sixes

A tied box game reaches the final horn. Does the next goal win, or must both teams finish an extra period? The competition’s rulebook—not simply the word “lacrosse”—decides. NLL and World Lacrosse box overtime ends with the first goal. World Lacrosse Sixes, under its 2026–2028 rules, uses full overtime periods instead.

“Sudden death” and “sudden victory” mean the same thing here: the first valid overtime goal ends the game. Neither team is guaranteed an answering possession.

Overtime rules at a glance

These are specific competition rules, not a universal rule for every club, school or tournament. Editions and upcoming changes are identified below.

Competition and rule edition	Overtime period	What decides the winner?
NLL, 2026–27, Rule 12	15 minutes	First goal wins; repeat periods if needed
World Lacrosse box, 2026–2028, Rule 5.4	15 minutes	First goal wins; repeat periods if needed
NCAA men’s field, 2027–2028, Rule 4-31	15 minutes	First goal wins; repeat periods if needed
NCAA women’s field, 2026–2027, Rule 4-8	5 minutes	First goal wins; repeat periods if needed
World Lacrosse Sixes, 2026–2028, Rule 5.1.4	3 minutes, stopped time	Play the full period; the team leading at its end wins. Repeat if tied

NCAA men’s timing is changing: the previous format used four-minute sudden-victory periods. The approved move to 15-minute periods is effective for the 2027 and 2028 seasons—do not apply it retrospectively to a 2026 spring game. NCAA explanation; approved changes and effective seasons

What happens in box overtime?

The NLL and World Lacrosse box procedures agree on the essentials:

• Take a two-minute interval after tied regulation.
• Begin overtime with a center faceoff.
• End the game as soon as the first valid goal is scored.
• If nobody scores in 15 minutes, take another two-minute interval, change ends and play another sudden-victory period.

Those procedures appear in NLL Rules 10.3, 12 and 44.1 and World Lacrosse box Rules 5.2.3, 5.4 and 6.2.1.

Imagine a team scores 40 seconds into overtime. The game is over; the remaining 14:20 is not played. A “15-minute overtime” describes the maximum playing time of that period, not a requirement to play all 15 minutes or a limit on elapsed time including stoppages.

The box 30-second shot clock still applies. Winning the faceoff creates an opportunity, not permission to hold the ball indefinitely. For a newcomer, watch two separate clocks: the game clock measures the period and stops during dead balls; the shot clock requires a shot on goal within 30 seconds of gaining possession. World Lacrosse box Rules 5.3 and 6.6; NLL Rules 11 and 49

Why Sixes needs a different expectation

Under World Lacrosse’s 2026–2028 Sixes rules, an early overtime goal does not end the game. The opposition can respond during the remainder of the full three-minute period. The game clock stops at every whistle during overtime. If the score is still tied at the period’s end, a two-minute break precedes another full period. There is also a two-minute break before the first overtime. Sixes Rules 5.1.4 and 5.2.2

Team timeout rules differ too. World Lacrosse box awards one timeout per team per sudden-victory period, with no carryover. World Lacrosse’s September 2026 Sixes interpretation says teams are not entitled to a timeout in overtime. Box Rule 5.6.1; Sixes interpretation, Rule 6.10.5

Before your own game

Ask the coach or organizer to confirm the adopted rule edition, whether a tie triggers overtime, whether overtime is sudden victory or a full period, and how opening possession, remaining penalties and timeouts will be administered. World Lacrosse explicitly allows national governing bodies to set implementation timelines and adapt its box rules, so an international rulebook is not automatically your local league’s procedure.
