Floyd Mayweather says he’s fighting Tenshin Nasukawa — although with what ruleset we’re unsure — later this year.

The undefeated boxer appeared at a RIZIN press conference earlier today in Japan to field questions from the press, albeit leaving some important details to be revealed (or just worked out) at a later date. According to Mayweather, he’ll face Nasukawa on New Years Eve later this year.
