Leon Edwards shook up the mixed martial arts world, knocking out Kamaru Usman with a stunning head kick late in the fifth round to become the new UFC welterweight champion Saturday night in the main event of UFC 278 in Salt Lake City.
The knockout came at 4 minutes, 4 seconds of a fight that Usman had largely dominated.
Edwards snapped Usman's 15-fight winning streak.
The fight was a rematch of a December 2015 bout, which Usman won by unanimous decision. Edwards has won 11 straight fights since that loss to Usman.
