Football

History of Football
The first documented gridiron football match was a game played on November 9, 1861, at University College, University of Toronto (approximately 400 yards west of Queen's Park). One of the participants in the game involving University of Toronto students was (Sir) William Mulock, later Chancellor of the school. A football club was formed at the university soon afterward, although its rules of play at this stage are unclear.[2]
In 1864, at Trinity College, Toronto, F. Barlow Cumberland and Frederick A. Bethune devised rules based on rugby football. However, modern Canadian football is widely regarded as having originated with a game of rugby played in Montreal, in 1865, when British Army officers played local civilians.[2] The game gradually gained a following, and the Montreal Football Club was formed in 1868, the first recorded non-university football club in Canada.
This rugby-football soon became popular at Montreal's McGill University. McGill challenged Harvard University to a game, in 1874.[4]
Predecessors of the Canadian Football League include the Canadian Rugby Football Union (CRFU), and the Canadian Rugby Union. The CRFU, original forerunner to the current Canadian Football League, was established in 1882.

Rules of the Game
Teams advance across the field through the execution of quick, distinct plays, which involve the possession of a brown, prolate spheroid ball with ends tapered to a point. The ball has two one-inch-wide white stripes.
Kickoff
Play begins with one team place-kicking the ball from its own 35-yard line. Both teams then attempt to catch the ball. The player who recovers the ball may run while holding the ball, or lateral throw the ball to a teammate.
Stoppage of play
Play stops when the ball carrier's knee, elbow, or any other body part aside from the feet and hands, is forced to the ground (a tackle); when a forward pass is not caught on the fly (during live play); when a touchdown (see below) or a field goal is scored; when the ball leaves the playing area by any means (being carried, thrown, or fumbled out of bounds); or when the ball carrier is in a standing position but can no longer move. If no score has been made, the next play starts from scrimmage.
Scrimmage
Before scrimmage, an official places the ball at the spot it was at the stop of clock, but no nearer than 24 yards from the sideline or 1 yard from the goal line. The line parallel to the goal line passing through the ball (line from sideline to sideline for the length of the ball) is referred to as the line of scrimmage. This line is a sort of "no-man's land"; players must stay on their respective sides of this line until the play has begun again. For a scrimmage to be valid the team in possession of the football must have seven players, excluding the quarterback, within one yard of the line of scrimmage. The defending team must stay a yard or more back from the line of scrimmage.
