According to UFC welterweight champion Kamaru Usman , he went into his most recent fight compromised. Usman (19-1 MMA, 14-0 UFC) revealed he broke his right hand three weeks prior to his rematch with Colby Covington at UFC 268 earlier this month, which he won by unanimous decision . Though Usman didn’t show any signs of his hand being affected when he knocked Covington down twice in Round 2, the champion says the injury happened during a sparring session with UFC lightweight contender and teammate Justin Gaethje, just a couple of weeks out of the fight.
