Lacrosse is the full contact team sport played using a small solid rubber ball and stick comprised of a plastic head and a metal or wood shaft. The head has a loose net strung into it that allows the player to hold the ball. Offensively the object of the game is to use the stick to catch, carry, and pass the ball in an effort to score by ultimately throwing the ball into an opponent's goal. Defensively the object is to keep the opposing team from scoring and to dispossess them of the ball through the use of stick checking and body contact. There are two main versions of the game; outdoor or field lacrosse and indoor or box lacrosse. The two versions of the sport differ in that field lacrosse is played with ten players to a side on a field roughly the size of a soccer pitch while box lacrosse is played with six players per side in an enclosure similar to that of an ice hockey rink.
