Basic information about the game of lacrosse
The Game
Lacrosse is played between two teams. The object of the game is to advance the ball into the opposing team's territory and shoot the ball into the opponent's goal. The team scoring the most goals at the end of regulation play is the winner. The ball is kept in play by being thrown, carried or hit by the stick, rolled or kicked by one or more players in any direction, as long as the ball stays in the field of play.
A team consists of 10 players; 1 goalie, 3 defensemen, 3 midfielders and 3 attackmen. Each team must keep at least 4 players, including the goalkeeper, in its defensive half of the field and 3 players in its offensive zone. The 3 midfielders are free to roam the entire field.
The game has four quarters, plus a halftime. Teams change ends between quarters. Youth games are generally 32 minutes long, with eight-minute quarters; two minute breaks between quarters and a ten-minute halftime. High school games are generally 40 to 48 minutes long with either 10 or 12 minute quarters and 10 minutes at halftime. Collegiate games are 60 minutes long with 15-minute quarters and a 15-minute halftime. Each team is permitted 4 timeouts, with a maximum of two in a half of play, and one additional timeout per each overtime sudden victory period.
The game starts at the center of the field with a face‑off. Face‑offs are also used to start each quarter and to resume play after each goal. The ball is placed on the ground and the two players facing off position their sticks back to back on either side of the ball, without touching the ball. The play starts when the official blows the whistle and face‑off players and other wing midfield players try to control the ball.
Players maneuver the ball by passing and/or running to gain an advantageous position, which will provide opportunities for a player to score a goal. Only the goalkeeper may touch the ball with his hands.
Players attempt to gain control of the ball by scooping or catching it with a stick or by dislodging the ball from an opponent's stick by checking. Checking involves poking, slapping or hitting an opponent's stick and gloved hand. Players may also attempt to gain possession of the ball by controlled body checks above the waist and below the shoulders from the front or side.
Attacking players may never enter the area immediately around an opponent's goal, known as the crease. Nor may a player physically touch the goalie while the goalie is in the crease. Should the goalie gain possession of the ball, opposing players may try to block the goalie's outlet pass (the clear) by standing in the goalie's line of sight and waving sticks. Opposing players may also reach into the crease to try to retrieve loose or ground balls, but may not interfere with the goalie.
Unlike other sports, should the ball go out of bounds after an unsuccessful shot, possession is awarded to the player closest to the ball where it went out of bounds at the moment the ball crosses the boundary line.
Field Positions
ATTACK: The attackman's responsibility is to score goals. He generally restricts his play to the offensive end.
MIDFIELD: The midfielder's responsibility is to cover the entire field playing both offense and defense.
DEFENSE: The defenseman's responsibility is to defend the goal. He generally restricts his play to the defensive end of the field.
GOALKEEPER: The goalie's responsibility is to protect the goal and stop the opposing team from scoring.
The Team
There is no limit to the total number of players each team may carry on its roster. Most teams carry six to nine defensemen, six to nine attackmen, nine to twelve midfielders and three goalies. This provides three complete rotations of players (4 for midfielders). This is only a general rule of thumb and will vary considerably based on availability of players and coaching philosophy. There can be a maximum of four long sticks on the field at any one time (not including the goalie). The remainder must be short sticks.
There will be situations (penalties) where one or both teams will be required to play with less than the full ten-member team. These are typically known as Man Up (the un-penalized team) or Man Down (the penalized team) situations and are usually handled with special field formations. Upon issuance of a penalty, which requires one or more players to go to the "Penalty Box," substitutes are not permitted to take their place. The team must play with a reduced number of players until the penalized players are released back onto the field by the officials.
The Field
The game is played on a rectangular field measuring 110 yards long by 53-1/3 to 60 yards wide. The field is marked at 55 yards from each end line with a center line and halfway across this centerline with an (X) to indicate the face‑off zone (see Figure 1).
Behind each goal there is a 15 yard space, and the goals are 80 yards apart. Twenty yards from each goal toward the center of the field there is a line called the defensive restraining line that spans the width of the field. The portion of the restraining line outside of the offensive box area is not shown in Figure 1.
Goals are typically manufactured of steel or aluminum tubing, measuring 6 feet square at the widest opening and converging to a point 7 feet behind the opening. A mesh net is tightly secured to goal. Each goal sits inside a circle with a radius of 9 feet, called the crease. The center of each crease is on the goal line (15 yards from the end lines) and midway between the sidelines.
OTHER IMPORTANT AREAS OF FIELD INCLUDE:
- Goal Area– also known as the "offensive box." It is the area inside the restraining lines at each end of the field. The lines parallel to the sidelines are 10 yards in from the sidelines and are dashed to avoid confusion with the sidelines.
- Defense Clearing Area ‑ area behind the defensive restraining lines which run across the field 20 yards in front of the goal.
- Wing Areas‑ indicated by two lines, 20 yards long and 10 yards in front of each sideline.
- "The Penalty Box" Area‑ is located directly in front of the officials' table and is used as a holding area for players to wait out their penalties. Penalized players must remain in the box, down on one knee. It is also the access area for substitute players entering and exiting the field.

Rules & Regulations
The game of lacrosse is a contact sport. Rules have been established which are intended to protect the safety of the players and maintain control over the game. Each game at the varsity level must have a minimum of two officials, who are called the referee and the umpire. There may also be a field judge and a chief bench official. Decisions regarding third and fourth officials are made by the organization hosting the game.
It is the coach's responsibility to teach and instill in each player an understanding of the nature of the game – it is a physical contact sport, but uncontrolled violent acts must not be tolerated. Players must be trained and are required to play with mental and physical control.
The NCAA has put forth comprehensive regulations and penalties for infractions. Following is a brief summary of some of the major, common rule violations.
PERSONAL FOULS are infractions of a serious nature, which carry suspension from the game for periods ranging from a minute to three minutes, depending on the severity and intent of the infraction. The penalty's length is usually one minute but can be up to three minutes at the discretion of the officials.
Cross
Check is a check by one player on another with the part of
the stick between the player's hands.
Slashing
occurs when a player swings his stick at an opponent in a
deliberate, vicious or reckless fashion, or when the stick comes in
contact with any part of the opponent other than on his stick or
gloves, unless the opponent is actively attempting to deflect a
legitimate check with part of his body. Slashing also occurs
when the stick of a player strikes any part of an opposing player's
body above the neck, unless when done by a player in the act of
shooting, passing or scooping the ball.
Illegal
Body Checks occur when checking a player not within 5 yards
of the ball, a late hit, contact from behind or above the shoulders
or below the waist. This also occurs when a body check is
thrown on an opponent who does not possess the ball, or when an
avoidable body check of the opponent is made after the opponent has
made a shot or pass.
Tripping
is obstructing an opponent at or below the waist with any part of
the stick or body. If a player makes a legitimate check with
the stick to dislodge the ball from an opponent's stick and
subsequently the opponent trips over his own or the checker's stick,
this is not tripping.
Stalling
is when a team intentionally holds the ball without advancing toward
the goal.
Holding
occurs when a player impede or interferes with an opponent's stick
movement
Off-Side
occurs when there are more than six players on the opponent's side
of the fields. This also occurs when a defenseman crosses the
center line as the ball is being cleared up the field and all three
attackmen and midfielders have progressed past the center line.
