Floyd Mayweather has signed a deal to fight on New Year's Eve -- and it might be an MMA match -- but it ain't against Conor McGregor or Khabib Nurmagomedov.
The boxing superstar just announced he'll be fighting at RIZIN 14 on New Year's Eve in Japan against an undefeated 20-year-old kickboxer named Tenshin Nasukawa.
Floyd says he's still working with the promotion to decide on whether it will be boxing rules, kickboxing rules, MMA rules, etc.
Floyd says the fighting rules will be sorted out in the coming weeks.
Floyd held a press conference in Japan late Sunday night -- Floyd did not say how much money he expects to make for the fight.
