If a player fumbles the ball through the end zone, the result of the play is a touchback.

In #KCvsBUF, when contact occurs to the receiver, the ball starts to move signaling loss of control.

This is a good overturn via replay to a fumble, resulting in a change of possession… https://t.co/j2uTKF8mLw
