A defensive position in football that lines up in the defensive
backfield and is mainly responsible for passing coverage. A safety
will cover the field of play and attempt to bat down or intercept
passes made by the offense or tackle a receiver who has caught the
ball. Safeties are mainly responsible for the middle of the field,
as the cornerbacks will cover the sides.
A safety is also the only scoring play in which the
defensive team can score two points by tackling the offense in its
own end zone. A "safety touch" is another way of getting
credit for the two points.
A safety is part of the defensive backs, along with cornerbacks, with two main types being the strong safety and the free safety. A strong safety will place himself on the strong side of the field where the most offensive weapons are placed, while the free safety is focused more on watching the play develop and anticipating where the pass is headed or where the defensive team is at its weakest.
