• All games are 12 vs. 12 format and will be governed by a version of NCAA Lacrosse Rules. We may play 8 vs 8 format which will be a game by game decision.
• 30 yard line restraining rule is in effect 4 players must stay back at all times. If we are playing 8 on 8, 2 players must stay back.
• When a whistle blows, all players must stop in place. When a ball is ruled out of play, the player closest to the ball gets possession when play is resumed. Loss of possession may occur if a player deliberately runs or throws the ball out of play.
• Field players may pass, catch or run with the ball in their crosse. A player may gain possession of the ball by dislodging it from an opponent's crosse with a check. A check is a controlled tap with a crosse on an opponent's crosse in an attempt to knock the ball free.
• The player must be one step in front of her opponent in order to check. No player may reach across an opponent's body to check the handle of a crosse when she is even with or behind that opponent. A player may not protect the ball in her crosse by cradling so close to her body or face so as to make a legal, safe check impossible for the opponent.
• All legal checks must be directed away from a seven-inch sphere or ""bubble"" around the head of the player. No player is allowed to touch the ball with her hands except the goalkeeper when she is within the goal circle. A change of possession may occur if a player gains a distinct advantage by playing the ball off her body.
• Rough checks, and contact to the body with the crosse or body, are not allowed.
• Fouls are categorized as major or minor, and the penalty for fouls is a “free position.” For major fouls, the offending player is placed four meters behind the player taking the free position. For a minor foul, the offending player is placed four meters off, in the direction from which she approached her opponent before committing the foul, and play is resumed. When a minor foul is committed in the critical scoring area, the player with the ball has an indirect free position, in which case the player must pass first.
• A slow whistle occurs when the offense has entered the critical scoring area and the defense has committed a major foul. A flag is thrown but no whistle is sounded so that the offense has an opportunity to score a goal. A whistle is blown when a goal is scored or the scoring opportunity is over. An immediate whistle is blown when a major foul, obstruction or shooting space occurs, which jeopardizes the safety of a player.
