Quarterback sack

In American football and Canadian football, a quarterback sack occurs when the quarterback is tackled behind the line of scrimmage before he can throw a forward pass. This often occurs if the opposing team's defensive line or linebackers are able to quickly get past blocking players of the offensive team, the quarterback's protection; or if the quarterback is unable to find, in a reasonable amount of time, an available receiver who can catch the ball, allowing the defense a longer opportunity to tackle the quarterback.
