Quarterback scramble

A quarterback scramble or scramble is an impromptu maneuver or run in American football and Canadian football by a quarterback. If a quarterback is under pressure by an opposing team's defense, he may run forward, backward, or laterally in an attempt to avoid being tackled behind the line of scrimmage—a quarterback sack. A scramble is not usually a designed play, but instead is the action of a quarterback to avoid being sacked by the defense or an improvised run forward to gain yardage if an opportunity presents itself.
