UFC's president, Dana White, has confirmed that star client Conor McGregor has agreed to terms with UFC for a boxing-rules super-fight with Floyd Mayweather.

"Conor and I have agreed on a deal," White said during a recent interview.

McGregor's contract with UFC was consider one major stumbling block to a potential fight.

Though "a bunch of lawyers" are looking over McGregor's agreement, White will present the terms to Mayweather adviser Al Haymon and Mayweather Promotions CEO Leonard Ellerbe this week.

Details of his discussion with McGregor are yet to be made public, but they won't have changed too much from the $75 million (£58 million) payday White mentioned last month.

If that is the case, it is likely former five-weight world champion Mayweather will be offered a larger fight purse of $100 million (£77 million).

This would be in line with the $100 million Mayweather received for outpointing Manny Pacquiao in 2015 (though he scooped a total of $200 million after pay-per-view earnings were finalized).

"It's either going to happen this year or it's never going to happen at all," White added, reiterating the "now or never" rhetoric used by Showtime earlier this month.
