The last time ​Floyd Mayweather was in a boxing ring was last August when he went 10 rounds and​ defeated UFC star Conor McGregor​, improving his record to 50-0. Mayweather announced his retirement after that fight, but it looks like he's coming back to fight a familiar foe. The 41-year-old posted a video saying he's going to fight ​Manny Pacquiao...again.

"I'm coming back to fight Manny Pacquiao this year. Another nine-figure pay day on the way," Mayweather said.

The last time Mayweather and Pacquiao fought in the ring was May 2015 in Las Vegas, with Mayweather winning by unanimous decision.

Their last fight was labeled "The Fight of the Century," but it certainly didn't turn out that way. "Money" Mayweather was in control from beginning to end. It probably wouldn't be any different at this stage of their careers, but just like Mayweather said, he'll be getting a nine-figure pay day.
