"It's possible. It's possible. There was a name that was shot at me. But the rumors that y'all have been hearing [are] the rumors I started," Mayweather said in video posted by FightHype.com. "It may not be a rumor. Keep your fingers crossed. It may be a boxer versus an MMA fighter. So we just don't know."
Mayweather, 39, didn't mention McGregor by name, but The Sun reported last week that Mayweather and McGregor were discussing a fight against each other, a report UFC president Dana White shot down by telling Yahoo! Sports, "It's not true. It's just a tabloid story."
