ground, otherwise, the player may stand up and continue to advance the ball. Hitting a player who is kneeling, sliding, or clearly intends to run the ball out of bounds (especially quarterbacks) is generally viewed as unsportsmanlike and is often penalized, and in the most blatant of cases (especially if it happens in the dying seconds of a game), the player may be subject to off-field disciplinary action by their respective league governing body, usually in the form of fines or suspensions. Overtime The procedures to settle games that are tied at the end of regulation vary considerably among football leagues. Most leagues other than the NFL, including the CFL, use a procedure frequently called the "Kansas Playoff", so named because it was first developed for high school-football in that state. The rules are summarized here: A coin toss at the start of overtime determines the team that first receives possession in overtime, and which end zone will be used. Each team in turn receives one possession starting with first-and-10 at a fixed point on the field, which varies according to league: US college (also Texas public high schools, which play by NCAA rules): Opponent's 25-yard line for the first two overtime procedures. Each procedure after the second consists of a single scrimmage play from the opponent's 3-yard line, with kicks banned. Successful plays in this situation are scored as two-point conversions. US high school (also British Columbia, where high schools play under American rules): Standard rules call for the opponent's 10-yard line, but state/provincial associations are free to use different yardage (Missouri, for instance, starts at the 25). The short-lived Alliance of American Football also used the opponent's 10-yard line. CFL: Opponent's 35-yard line The game clock does not run, but the play clock is enforced. At all levels, possessions end when the offensive team scores, misses a field goal, or turns the ball over. Touchdowns are followed by a conversion attempt, with the following additional caveats: US college: Teams must attempt a two-point conversion starting with double overtime. From triple overtime & thereafter, all plays are two-point conversion attempts, and scored as such. CFL and AAF: A convert kick is not allowed in overtime—all conversion attempts must be scrimmage plays (i.e., two-point attempts). US and BC high school: Standard rules call for no restrictions on the type of conversion attempt, but some state/provincial associations may limit the use
