Floyd Mayweather denies claims he is in negotiations to fight in the UFC

UFC President Dana White claimed talks were underway to get Floyd Mayweather in the Octagon, but the 15-time world boxing champion said Thursday that it's not true.

White said the prospect of a Mayweather UFC deal was "real" after color commentator Joe Rogan, who is close friends with White, revealed that the UFC chief told him via text that Mayweather wanted to make a deal.

But Mayweather all but killed off talk of a potential crossover fight.

"I never said I was going to fight in the UFC," Mayweather told FightHype. "I didn't say that. I said if I wanted to, and what I could do. Would and could do is different things. I'm not going to do it though.

Mayweather reiterated comments he made earlier this month that he could make $1 billion if he fought in the UFC.

"They talk about 'oh yeah Floyd said he's fighting in the UFC for a billion dollars.' That's not what I said.

"Exactly what I said is this: If I made over a billion dollars before, I could do it again. If I chose to get in the UFC and fight three fights or four fights and then fight Conor McGregor, which I can. I could do it in three fights, or even four fights. I can make a billion dollars if I choose to get in the octagon and fight.

"We just don't know what the future holds for Floyd Mayweather, and I don't look forward to getting back in the boxing ring. That's what I don't look forward to. I'm just saying I could. I'm not going it, but I'm saying what I could do to make a billion dollars quick if I wanted to do it. That's what I am saying."
