In American football and Canadian football, a quarterback kneel, also called taking a knee, genuflect offense, kneel-down offense, or victory formation, occurs when the quarterback touches a knee to the ground immediately after receiving the snap, thus downing himself and ending the play. It is primarily used to run the clock down, either at the end of the first half or the game itself, to preserve a lead or ensure a game goes into overtime if the game is tied and in the fourth quarter. Although it generally results in a loss of some yardage and uses up a down, it minimizes the risk of a fumble, which would give the other team a chance at recovering the ball.

The quarterback, colloquially known as the "signal caller", is a position in gridiron football. Quarterbacks are members of the offensive platoon and mostly line up directly behind the offensive line. In modern American football, the quarterback is usually considered the leader of the offense, and is often responsible for calling the play in the huddle. The quarterback also touches the ball on almost every offensive play, and is almost always the offensive player that throws forward passes. When the QB is tackled behind the line of scrimmage, it is called a sack.
