Kamaru Usman has ONLY lost 1 time in his historic MMA career ... and the only man to beat him, fighter Jose Caceres, says the Nigerian Nightmare can't, won't, lose to Colby Covington.
34-year-old Caceres faced Kamaru in 2013 ... beating the now champ via a rear-naked choke in the 1st round (it must be said -- this was Usman's 2nd pro fight).
Jose also happened to fight Covington ... losing to Colby, also in 2013, via unanimous decision.
But, even though he beat Usman and lost to Covington, Caceres says he knows who's gonna win when the men do battle again at UFC 268.
"That kid has the most chances of winning. I look at it like the human body. He's really developed like the anti-virus, the vaccine for Colby Covington. He kinda already knows how to beat him. He already experienced 5 rounds of him," Caceres says.
Of course, Kamaru and Colby fought in 2019 -- an amazing fight -- won by KU via 5th round TKO.
Now the men are about to scrap again ... and the question is, will Jose remain the only man to take down the Nigerian Nightmare??
