Former five division world champion Floyd Mayweather has confirmed that he's considering another exhibition bout, which could take place in 2020 or 2021.

Mayweather snapped a two year retirement in 2017, when he stepped in the ring and stopped UFC superstar Conor McGregor in the tenth round at the T-Mobile Arena in Las Vegas.

The crossover bout was the second biggest pay-per-view in combat sports history. And Mayweather once again retired in the aftermath, with a perfect record of 50-0.

Mayweather came back to the ring on New Year's Eve in 2018, in Japan, for a very lucrative exhibition bout where he demolished Tenshin Nasukawa in the first round.

That card was promoted by Japanese combat sports promotion Rizin.

Mayweather is once again in talks with Rizin, confirming overseas reports that he's discussing another lucrative exhibition opportunity.

“We’re working on some things right now for Tokyo, whether 2020 or 2021,” Mayweather said to Forbes.

“For now, I'm happily retired. You never know, but it would have to be worth it. Just like gambling right? Juice worth the squeeze no matter who the opponent is.”

For the last two years, Mayweather has been teasing the scenario of a ring return - including some hints that he would enter the cage for a McGregor rematch.

But Mayweather has now denied the consistent rumors of potentially crossing over to mixed martial arts. He sees no viable reason to give away an advantage to any opponent.

“No [I won’t compete in MMA],” Mayweather. “I think just like how winning teams receive home-field advantage in the playoffs...you don't fix what isn't broken, and my record isn't broken.”
