 If the kick returner catches the ball in his own end zone, he can either run with the ball, or elect for a touchback by kneeling in the end zone, in which case the receiving team then starts its offensive drive from its own 20-yard line (25-yard line in NFL, since 2015).A touchback also occurs when the kick goes out-of-bounds in the end zone, or since 2018, the ball hits the ground on the goal line and in the end zone.A kickoff that goes out-of-bounds anywhere other than the end zone before being touched by the receiving team is a foul, and the ball will be placed where it went out of bounds or from the kickoff spot, depending on which is more advantageous to the opposite team.
