Floyd Mayweather just can't retire--or quit Conor McGregor. The decorated boxer now tells TMZ Sports that he wants a rematch with the polarizing MMA fighter after an upcoming to-be-scheduled match with Khabib Nurmagomdov. "McGregor was talking that s**t, so it ain't over," Floyd told TMZ Sports. "After me and Khabib lock up, me and McGregor we gonna lock up again." Mayweather also clarified why he keeps tangling with so many MMA fighters, citing "crazy numbers" as the reason, among several others. "I'm helping keep combat sports alive!" In any case, he also shed some insight into why he continues fighting. "I'm ready to go out there and get the job done and entertain," he says. "'Cause McGregor-Mayweather was real entertaining. I gave people what they wanted to see."
