The rules for outdoor men's lacrosse
Outdoor men's lacrosse involves two teams, each competing to project a small ball of solid rubber into the opposing team's goal. Each team starts with ten players on the field: a goalkeeper or "goalie" who stays inside the crease; three defenders in the defensive end; three midfielders free to roam the whole field; and three attackers attempting to score goals in the offensive end.
Players scoop the ball off the ground with their stick and may run carrying the ball in their stick, pass the ball through the air to other players, or throw it at the goal. In men's lacrosse, players may kick the ball, as well as cover it with their sticks, provided they do not withhold it from play.
Play is quite fast and fluent, with considerably more goals scored than are in soccer or hockey, with typical games totaling ten to twenty goals.
Each quarter starts with a “face-off” in which the ball is placed on the ground and two “face-off-men” lay their stick horizontally next to the ball, head of the stick inches from the ball and the butt-end pointing down the midfield line. Face-off-men scrap for the ball, often by “clamping” it under their stick and flicking it out to their midfielders, who start on the wing restraining line near the sideline and sprint in when the whistle is blown to start play. Attackers and defenders cannot cross their “restraining line” until one player from the midfield takes possession of the ball. A face-off also restarts the game after each goal.
