That's not the case, according to UFC President Dana White, who addressed the issue in his post-fight media scrum this past weekend.
"They say [Vitor] can't fight here because of the TRT thing and that is complete bullshit. Vitor Belfort can fight here, he can fight in Vegas, he can fight in any of these places. Whether they give him TRT or they don't. It's not a given that he has to give up the treatment in Vegas. The guy has been busted before. He's had some issues and he's going to have to go before the athletic commission and they would decide what they are going to do."
White further elaborated that just because Belfort needs to go before the commission to get approval for TRT, that doesn't mean UFC is protecting him by keeping him in Brazil lately. They've done it for a very specific reason and that's because the popular Brazilian fighter puts butts in seats.
"That doesn't mean that he can't fight in Vegas or that Vitor Belfort is banned from Vegas and something crazy is going to happen. Or that we're hiding him in Brazil because he's on TRT. That is stupid, stupid Internet shit. Vitor Belfort is a big draw in Brazil so he fights in Brazil. Same thing with Aldo and a lot of these other Brazilian champions. If any of you have ever been to Brazil, Brazilians want to see Brazilians kick other people's asses, not other Brazilian's asses."
