The champion found his rhythm midway through the fight, but still competed cautiously and didn’t even attempt a late takedown of his hobbling opponent.
Earlier, Amanda Nunes defended her bantamweight title with a spectacular head kick leading to a stoppage of Holly Holm in the first round. Nunes remained the pound-for-pound ruler of her sport.
She floored Holm with a kick to the head, and finished Holm on the ground with 50 seconds left in the first round. Holm is a veteran boxer and kickboxer who upset Ronda Rousey to win the bantamweight belt, but Nunes is on another level than every 135-pounder before her.
Earlier, Jorge Masvidal knocked out fellow American Ben Askren with a sensational flying knee just five seconds into their bout.
Masvidal delivered the fastest knockout in UFC history in jaw-dropping fashion.
After listening to the opening bell while touching his own fence, Masvidal took three running steps out of his corner and sailed directly into the face of Askren (19-1), who had never been beaten in his 10-year pro mixed martial arts career.
Masvidal landed two punches to the unconscious Askren’s head before the referee could stop the bout.
