FLOYD MAYWEATHER JR has refused to rule out stepping into the ring with Conor McGregor for a multi-million dollar fight.

Speculation that the undefeated five-division world champion boxer could face Irish MMA star McGregor emerged last week with The Sun reporting that the pair were on the verge of agreeing a match-up in Las Vegas this summer.

A bout between two of the biggest names in their respective sports would undoubtedly generate huge interest and, when asked about the rumours, 39-year-old Mayweather claimed that it could happen.

“It’s possible,” Mayweather told Liftn com. “It (McGregor) was a name that was shot at me. The rumours that y’all been hearing is the rumours that I started.

It may not be a rumour so keep your fingers crossed. It may be a boxer versus an MMA fighter — we just don’t know.”

McGregor, who was pulled from his rematch with Nate Diaz at UFC 200 after refusing to comply with media obligations last month, also posted a mock-up poster featuring him and Mayweather on his Facebook and Twitter accounts this afternoon.
