The sport originated among Native Americans, and the modern rules of field lacrosse were initially codified by Canadian William George Beers in 1867.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.[2][3] According to Native American beliefs, playing lacrosse is a spiritual act used for healing and giving thanks to the "Creator".[7][11] In 1867, Montreal Lacrosse Club member William George Beers codified the modern game.A lacrosse ball is made out of solid rubber, measuring 7.75 to 8 inches (19.7–20 cm) in circumference and weighing 5 to 5.25 ounces (140–149 g).Players are required to wear some protective equipment, and must carry a lacrosse stick (or crosse) that meets specifications.[16] If a player enters the "crease" while shooting toward the goal, the referee will call a foul and the ball gets turned over to the other team.The head is roughly triangular in shape and is loosely strung with mesh or leathers and nylon strings to form a "pocket" that allows the ball to be caught, carried, and thrown.The sport's growth has been hindered by the cost of a player's equipment: a uniform, helmet, shoulder pads, hand protection, and lacrosse sticks.[20][21] The introduction of the plastic heads in the 1970s gave players an alternative to the wooden stick,[5] and their mass production has led to greater accessibility and expansion of the sport.[16] A goalkeeper needs to stop shots that are capable of reaching over 100 miles per hour (160 km/h), and is responsible for directing the team's defense.The head of a goalkeeper's crosse may measure up to 15 inches (38 cm) wide, significantly larger than field players'.The method of breaking a tie generally consists of multiple overtime periods of 5 minutes (4 in NCAA play, 10 in [MLL/PLL]) in which whoever scores a goal is awarded a sudden victory.[34][35] International lacrosse plays two straight 5-minute overtime periods, and then applies the sudden victory rule if the score is still tied.Offensive players are responsible for "riding" opponents, in other words attempting to deny the opposition a free "clear" of the ball over the midfield line.Both unsportsmanlike conduct and unnecessary roughness are subject to the officiating crew's discretion, while equipment violations are governed strictly by regulations.Technical fouls include holding, interference, pushing, illegal offensive screening (usually referred to as a "moving pick"), "warding off", stalling, and off-sides.As with a personal foul, until the penalty time expires, no replacement for the player is allowed and the team must play one man short.The player (or a replacement) is allowed to reenter the game once the time in the penalty box is over and the team is thus once again at full strength.College lacrosse, a spring sport in the United States, saw its earliest program established by New York University in 1877.[7][40] The United States Intercollegiate Lacrosse Association (USILA) was created in 1885, and awarded the inaugural Wingate Memorial Trophy to the University of Maryland as national champions in 1936.[44][45][46] Lacrosse was first witnessed in England, Scotland, Ireland and France in 1867 when a team of Native Americans and Canadians traveled to Europe to showcase the sport.[49] The country sponsors various competitions among its states and territories that culminate in the annual Senior Lacrosse Championship tournament.In order to qualify, the Blue Jays won tournaments in the Olympic years to represent the United States.In the past, in order to be considered as an Olympic sport the game had to be played on four continents, and with at least a total of 75 countries participating.[74][75] In October 2023, the LA28 Organizing Committee announced that it had recommended lacrosse as one of five sports that may be added to the program for the 2028 Summer Olympics.The 2008 Under-19 World Lacrosse Championships included twelve countries, with three first-time participants: Bermuda, Finland, and Scotland.[85] The 2007 NCAA Division I Men's Lacrosse Championship weekend held at M&T Bank Stadium in Baltimore, Maryland, was played in front of a total crowd of 123,225 fans for the three-day event.[86] The current attendance record for a regular season lacrosse-only event was set by the 2009 Big City Classic, a triple-header at Giants Stadium which drew 22,308 spectators.[87] The Denver Outlaws hold the professional field lacrosse single-game attendance record by playing July 4, 2015 in front of 31,644 fans.
