Kavanagh, who is currently in Australia, told a press conference that he believes the long pined for fight with the undefeated five-division champion Floyd Mayweather could happen by the end of summer 2017.

He said “What I see happening this year is the Mayweather fight, maybe the end of the summer or something like that.

The Ultimate Fighting Championship President Dana White, who had initially suggested the McGregor would not be permitted to fight Mayweather due to his UFC contract has finally revealed that he will allow the Dubliner into the boxing ring.

Speaking on the Chris Mannix Show he said ”I am [negotiating the terms for that fight] – Conor has been a guy who has stepped up in times of need here, so I want to do this for Conor.”

He added “I want him to be able to make this kind of money…I think we’re actually there, I just need to get together with him and finalize some stuff and then it’s onto Mayweather."
