"They didn't like my style, they didn't like that I wasn't entertaining. This is before I really started to become an entertainer and really understand the entertainment aspect of the business.
"Before this fight, they told me no matter what happens, I was ranked No. 6 in the world, we're not re-signing you, we don't like your character, we don't like your fighting style.
"So I go out there and I beat him up and leave him in a pool of blood in Sao Paulo, in his home city. I shoot this promo on the Brazilians and say, 'You guys are all a bunch of filthy animals and Brazil you're a dump.'
"That promo goes so viral, that the UFC's like, we have to keep him, we have to re-sign him because that promo is so big. So that's what saved my career and that was the turning point of my career. The rest has been history."
The surprise admission from Covington caught fellow fighters by surprise who were quick to call him out for the act with his opponent, Usman, ripping into him.
"This is him trying to make excuses why he's going to get his a** kicked on Sunday," Usman said during the UFC 245 athlete panel.
"He's already come out and said, 'Oh, this is just an act.' I don't give a (expletive). He came out and said, 'They were going to cut me, so it's just an act.' You (expletive) nerd. It doesn't matter. After you get your a** kicked you can do whatever you want to do. I don't care."
