In American and Canadian football, a kick returner (KR) is the player on special teams who is primarily responsible for catching the opposing team's kickoff and attempting to run it towards the end zone to score a touchdown. If the ball is kicked into his own end zone, the kick returner must assess the situation on the field while the ball is in the air and determine if it would be beneficial to his team for a return. If he decides that it is not, he can make a touch back by kneeling down in the end zone after catching the ball, ending the play and starting the next play at the 20-yard line to start the drive.
