Chop block (gridiron football)
Gridiron football term
In gridiron football, a chop block is an attempt by an offensive player to cut block (block at the thigh level or lower) a defensive player while the defender is already engaged by another offensive player. The chop block is usually considered illegal and penalized by a loss of 15-yards due to the injury risk it presents to the defender.[1]
