A fumble in football is a turnover that happens when the ball carrier drops the ball and it is recovered by a defensive player. On a fumble the ball can be knocked out of the ball carrier's hands. A fumbled ball is a live ball and can be recovered by any player on the field of play.
You can recognize a fumble when a player with the ball drops it or loses control of it. Fumbles must happen before a player is tackled or run out of bounds. Almost any means of the player dropping the ball counts as a fumble, whether the player loses his grip on the ball or an opposing team member pushes it out of his hands. Whoever gets possession at the end of the fumble keeps the possession.
Since loose footballs can bounce in any direction, it can be dangerous for players to go after them. Many coaches prefer their players to fall on the ball to regain possession. This eliminates the possibility of injury, since many pileups occur at the sight of a fumble. A player should fall on top of the ball, hugging it tightly to their stomach with their head tucked in until the official signals a stoppage in play.
A fumble in football is when a player carrying the football loses control of the ball and drops it before they are tackled to the ground. When the ball is fumbled, it is a live ball and either team can recover it. The team who recovers a fumble is awarded possession of the ball. A fumble can also occur on a lateral pass, where a player attempts to pitch the ball back to another teammate. If the ball is dropped or missed on a lateral pass, it is a live ball. If the ball rolls out of bounds after being fumbled, the team who fumbled retains possession of the ball and the ball is placed at the spot of the fumble. Before a fumble can occur, the player carrying the ball must declare possession by making a 'football move', i.e. bringing the ball to the chest, taking multiple steps, etc.
