An interception or intercept is a move in football that happens when a player on the defensive team catches a ball from the quarterback instead of the intended receiver. When this is done, the player's team who had caught the ball, would gain possession of it. Many leagues use interceptions, some are Canadian football and American football, as well as rugby league, rugby union, Australian rules football and Gaelic football. The most common players to get interceptions are defensive backs.
