Floyd Mayweather Jr. isn't shooting down rumors that he might come out of retirement to fight mixed-martial star Conor McGregor.
"It's possible. It's possible. There was a name that was shot at me," Mayweather said Saturday in a video posted on the boxing website FightHype.com. "But the rumors that y'all have been hearing (are) the rumors I started. 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."
