Floyd Mayweather will come out of retirement only if fight with Conor McGregor is confirmedGetty

Retired professional boxer Floyd Mayweather has claimed that he will only make a comeback if drawn to fight Ultimate Fighting Championship (UFC) superstar Conor McGregor. Mayweather retired with a career record of 49-0, that is 49 wins and zero losses, and is tied with legendary boxer Rocky Marciano.

The 39-year-old sent the boxing world into a frenzy earlier in May when he stated that he would return to boxing only for a "nine-figure payday". However, now it looks like he has backtracked from that statement.

"If I do fight, it's only against Conor McGregor, not against anybody else. Because the match-up is so intriguing. You have a boxer against an MMA fighter — one of the best MMA fighters to ever stand up and do it. He's a strong fighter and when I look at his fights, he's a little faster than I thought he was," Mayweather was quoted by Fox sports as saying.

Both Mayweather and McGregor have been teasing fans with the prospect of a match-up, with McGregor even tweeting a mocked-up poster of the two. The former professional boxer, though, has said the fight will be under boxing rules and the money involved will be very high, more than what he and Manny Pacquiao got in 2015.

"We probably could break that number, anything is possible. I'm pretty sure we're going to have a master plan to make that fight happen. It hasn't happened yet, but we locked down some dates, me and my team. We locked down some dates, in different countries, in different cities in the United States.

"I think it will be so entertaining, if we can do it. If we can put a boxer with an MMA fighter. I can't overlook that guy. We haven't made the fight happen yet, but if we could tweak a few things, I'm sure we could get him, not a good pay-day, but a great pay-day," McGreogor said.
