Men's 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 release; the other players must wait until one player has gained possession of the ball or the ball has crossed the goal line.
Center face-offs are also used after a goal and at the start of each quarter.
Players may run with the ball in the crosse, pass and catch 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, which includes the controlled poking and slapping of the stick and gloved hands of the player in possession of the ball.

If the ball or a player in possession of the ball goes out of bounds, the other team is awarded possession of the ball. If the ball goes out of bounds after an unsuccessful shot on goal, the player nearest to the ball when and where it goes out of bounds is awarded possession.
