Rizin has featured MMA, kickboxing, shootboxing, tag team grappling, and now can add bare-knuckle boxing to its resume. At a press conference on Thursday, Rizin CEO Nobuyuki Sakakibara announced that former K-1 kickboxer Tatsuki Shinotsuka would be one of the opponents. The other opponent has not been announced at this time but it was said it could either be a foreign or Japanese fighter.
