Hasim Rahman Jr. is fired up ahead of his August 6 with Jake Paul at Madison Square Garden.
After the 31-year-old was brought in as a replacement for Tommy Fury, UFC President Dana White wasn't afraid to criticise the move and didn't understand why Paul had picked an opponent who lost his last fight.
When asked on The DAZN Boxing Show to respond to the comments, Rahman Jr. didn't hold back and claimed he could hold his own against some of the UFC's best heavyweights.
"First of all, I wasn’t knocked out, I got stopped, I was on my feet," Rahman Jr. said.
"Dana White could put anyone in there with me, Francis Ngannou, Jon Jones, the retired dude Randy Couture, I would destroy them, he knows that.
"He’s not going to put any of his fighters with me so I don’t put much weight on what he said.
"He doesn’t want his fighters fighting boxers anyway, and I can get in a cage with these guys too.
"I’m a real fighter."
While White may have been happy to make those comments at a press conference, Rahman Jr. claimed there would be different comments from White if the pair were to meet face-to-face.
"He would never talk to me like that to my face.
"He is one of the fakest people in combat sports, so I’m actually glad that Jake Paul has been exposing him as far as how fake he is in the combat sports world."
