Undefeated boxer Floyd Mayweather Jr. is now set to face off against Tenshin Nasukawa at Rizin 14 on Dec. 31. The bout will take place under "special rules," though the specifics of the bout's rule set have yet to be revealed. "Money" Mayweather returned to retirement back in 2017, but has since come back to the world of combat sports for the upcoming match up. Speaking at Rizin's recent press conference for the official announcement of the match up, Floyd Mayweather Jr. offered a few words on the bout. “This kid right here is very special. He’s young, very fast, and he is undefeated. It’s obvious he’s been doing something right to be where he is at, so I’m proud of him. It doesn’t matter where the fight is at, but it’s in a special place. I’m pretty sure he’s going to bring a lot of excitement. I’m going to bring a lot of excitement. And that’s what the people want to see.” “The weight class and the rules, we will get that situated within the next couple weeks. This particular bout is a special bout as we are giving people something they have never seen before. The world has never seen Mayweather compete live in Tokyo. When it’s all said and done, it’s about me going out there and displaying my skills against another skillful fighter.” For more MMA news click here.
