Tournament Rules

All registered players and coaches must be current members of USA Lacrosse.

Registration is open to any player, or team of players, under the age of 18 and members of USA Lacrosse. Players may form their own teams solely for the purpose of the tournament, but must plan to have an adult present and on the team side-line to serve as a coach on the day of the tournament. Players may also register as individuals and will be placed on a team with other individual registrants at the selected division level.

Teams and players may play up a division, but they may not play down a division or age group.

All high school, U14 and U12 games are anticipated as full field games. All U10 games will be half field.

There will be one central horn used for all timing.

Timing: games are currently projected to have two 20 minute halves, 5 minute half time, running clock, and 5 minutes between games. Timing may change depending on the number of Registrants, but games will not be shorter than the projected timing.

The ATX 2025 Zebra Open Girls' Lacrosse Tournament will follow all USA Lacrosse and NFHS Rules as it pertains to each age level with some specific modifications, to be determined based on final timing and registration numbers. Full tournament rules will be posted here and emailed to Registrants by September 10, 2025.
