Mouthy Conor McGregor promises to knock Floyd Mayweather’s head off in ‘billion-dollar Vegas fight’ – but seems he has business to take care of first

Conor McGregor has promised to knock Floyd Mayweather’s head off if the pair come face-to-face in what has been billed as Las Vegas’ first-ever billion dollar fight.

The Irish UFC star has fired shots at the boxing champion as it was claimed that the pair reached an agreement to fight after months of intense negotiations between their management teams.

I am in Las Vegas. Floyd has retired on my arrival.

The Sun reported that the hotly-anticipated match could be Las Vegas’ first-ever billion-dollar fight with the two cash cows feuding with each other video social media for the best part of a year.

Mayweather recently said, according to ESPN, that the two camps were “very, very close” to making the agreement and it looks like it’s been inked.Ahead of the match, which would see 28-year-old UFC star McGregor cross over into boxing to take on the undefeated boxing legend Mayweather, 39, McGregor has vowed to knock the American star’s block off.

“Honestly, my fist is bigger than his head. I sleep people. I put people unconscious. I’m stating facts. If I hit a man, his head is gonna go into the bleachers. You understand that?” he said, according to TMZ.

“If I crack that little head of his, it’s gonna go clean off his shoulder and up into the bleachers.”

But while McGregor is good at talking the talk – his people don’t appear to have reached the agreement, according to Floyd.

Sharing on Instagram yesterday, Mayweather wrote: “There seems to be several rumors floating around media recently however, let the record show, there hasn’t been any deals made in regards to a fight between myself and any other fighters. I am happily retired and enjoying life at this time. If any changes are to come, be sure that I will be the first to let the world to know. (sic).”

He also added: “Listen, Conor McGregor, if you really want to get this fight done… take care of your business with the UFC and then have your people get in touch with my people.”
