Boyslacrosse is a contact game played by ten players: a goalie, three defensemen, three midfielders and three attackmen. The object of the game is to shoot the ball into the opponent’s goal and to keep the other team from scoring. The team scoring the most goals wins.
Each team must keep at least four players, including the goalie, in its defensive half of the field and three in its offensive half. Three players (midfielders) may roam the entire field.
Collegiate games are 60 minutes long, with 15-minute quarters. Generally, high school games are 48 minutes long, with 12-minute quarters. Youth games vary by level; please refer to the Boys' Youth Rules section from the main index. Each team is given a two-minute break between the first and second quarters, and the third and fourth quarters. Halftime is 10 minutes long.
Teams change sides between periods. Each team is permitted two timeouts each half. The team winning the coin toss chooses the end of the field it wants to defend first.
The players take their positions on the field: four in the defensive clearing area, one at the center, two in the wing areas and three in their attack goal area.
Men’s/boys' lacrosse begins with a face-off. The ball is placed between the sticks of two squatting players at the center of the field. The official blows the whistle to begin play. Each face-off player tries to control the ball. The players in the wing areas can run after the ball when the whistle sounds. The other players must wait until one player has gained possession of the ball, or the ball has crossed a goal area line, before they can release.
Center face-offs are also used at the start of each quarter and after a goal is scored. Field players must use their crosses to pass, catch and run with the ball. Only the goalkeeper may touch the ball with his hands. A player may gain possession of the ball by dislodging it from an opponent’s crosse with a stick check. A stick check is the controlled poking and slapping of the stick and gloved hands of the player in possession of the ball.
Body checking is permitted if the opponent has the ball or is within five yards of a loose ball. All body contact must occur from the front or side, above the waist and below the shoulders, and with both hands on the stick. An opponent’s crosse may also be stick checked if it is within five yards of a loose ball or ball in the air. Aggressive body checking is discouraged.
If the ball or a player in possession of the ball goes out of bounds, the other team is awarded possession. If the ball goes out of bounds after an unsuccessful shot, the player nearest to the ball when and where it goes out of bounds is awarded possession.
An attacking player cannot enter the crease around the goal, but may reach in with his stick to scoop a loose ball.
A referee, umpire and field judge supervise field play. A chief bench official, timekeepers and scorers assist. There are personal fouls and technical fouls in boys’ lacrosse. The penalty for a personal foul results in a one-to-three minute suspension from play and possession to the team that was fouled. Players with five personal fouls are ejected from the game. The penalty for a technical foul is a 30-second suspension if a team is in possession of the ball when the foul is committed, or possession of the ball to the team that was fouled if there was no possession when the foul was committed.
The US Lacrosse Youth Council has adopted modified rules for play by youth ages 15 and under. The official rules can be found by following the rules link on the main index. The rules are provided as modifications to the National Federation of State High School Associations rule book, which governs high school play. College play is governed by the NCAA rulebook.
The attackman's responsibility is to score goals and help his teammates score goals by passing the ball. The attackman generally restricts his play to the offensive end of the field. A good attackman demonstrates excellent stick work with both hands and has quick feet to maneuver around the goal. Each team has three attackmen on the field during play.
The midfielder's responsibility is to cover the entire field, playing both offense and defense. The midfielder is a key to the transition game, and is often called upon to clear the ball from defense to offense. A good midfielder demonstrates good stick work including throwing, catching and scooping. Speed and stamina are essential. Each team has three midfielders on the field.
The defenseman's responsibility is to defend the goal. The defenseman generally restricts his play to the defensive end of the field. A good defenseman should be able to react quickly in game situations. Agility and aggressiveness are necessary, but great stick work is more essential to attack. Each team has three defensemen on the field.
The goalie's responsibility is to protect the goal and stop the opposing team from scoring. A good goalie also leads the defense by reading the situation and directing the defensemen to react. A good goalie should have excellent hand/eye coordination and a strong voice. Quickness, agility, confidence and the ability to concentrate are also essential. Each team has one goalie in the goal during play.
