 | | Canadian football is a close relative to the sport with a few key differences; the word "football" in Canada can mean American football or Canadian football depending on context. |
 | | Most penalties result in moving the football either towards the endzone in the case of a defensive penalty, or away from the endzone in the case of an offensive penalty. |
 | | Tackle football is often banned in American schoolyards in favor of touch football, which uses two-hand touching instead of tackling; or flag football in which a player is "tackled" when an opponent pulls a flag off a belt attached to the player's waist. |
