How many players start the match on a men's field lacrosse team?

Lacrosse is a contact team sport played between two teams using a small rubber ball (62.8–64.77 mm (2.472–2.550 in), 140–147 g (4.9–5.2 oz)) and a long-handled stick called a crosse or lacrosse stick. It is often considered as a rough sport, with slashes and intense checks to the stick and body. The head of the lacrosse stick is strung with loose mesh designed to catch and hold the lacrosse ball.

Offensively, the objective of the game is to score by shooting the ball into an opponent's goal past the goalie, using the lacrosse stick to catch, cradle, and pass the ball to do so. Defensively, the objective is to keep the other team from scoring and to gain the ball through the use of stick checking and body contact or positioning. The sport has four major types: men's field lacrosse, women's lacrosse, box lacrosse and intercrosse.

There are ten players in each team:

A lacrosse field is split into halves that determine who is on offense or defense. A team can have no more than six players on offense, usually three attackmen and three midfielders. Also, it can have no more than seven players on defense, usually three midfielders, three defensemen and one goalie.

Women’s lacrosse is played with a team of 12 players, including the goalkeeper during usual play.
