Mayweather v McGregor Fight NOT the Richest in Boxing History - Showtime

The much publicised bout, which also stirred considerable controversy, comes in as the second richest in the history of the sport after generating 4.3 million pay-per-view buys, according to a statement from Showtime sports.

Mayweather claims the deal could encompass up to four fights.

In a chance interview with entertainment website TMZ, McGregor said he wants to be in a "real fight". Then there were McGregor-Pacquiao murmurs.

"A think a true fight is what I want to do next", McGregor said to TMZ. "A real fight".

Showtime said in their statement that the fight had exceeded 600 million dollars, including global revenues, including ticket sales, sponsorship and worldwide distribution.

"If we can negotiate it, I have no problem".

McGregor hasn't fought in UFC since winning the 155-pound title in November 2016 by knocking out Eddie Alvarez and has not defended the title. "I'm going to get my shoulder fixed and I'm going to watch the game be as ridiculous as it's been and see who's next".

They just called me not too long ago and asked me to come back. Originally, he was saying an MMA bout next. I can come right back.

The historic clash on August 26 saw the Irish UFC star make his professional boxing debut against Mayweather, an unbeaten former five-weight world champion. I earned their respect and put myself out there.
