Block in the back
In gridiron football, a block in the back is an action in which a blocker contacts a non-ballcarrying member of the opposing team from behind and above the waist. The foul is called when the area blocked is between the shoulder pads. It is against the rules in most leagues, carrying a 10-yard penalty.
