In the American sport of gridiron football, teams can score in a variety of ways, including through six-point touchdown plays and three-point field goals. Other scoring plays, such as a successful two-point conversion following a touchdown or a safety, are less common. However, perhaps the rarest scoring play in football is valued at one point.
A traditional safety occurs when an offensive player carrying the football is tackled in his own end zone. The defensive team automatically scores two points on the safety and kicks off to the opposing team. A one-point safety, on the other hand, can only occur during a one- or two-point conversion attempt. Should the defense gain possession of the football before being tackled in its own end zone, a safety is called and the tackling team receives a single point.
