Anpo’s move to ONE has been in the works since last year, when he revealed he was in talks with the promotion and open to competing without committing to a long-term contract. After leaving K-1, he stayed active with appearances in RIZIN and crossover bouts, but now steps back into the division’s deep end.

Grigorian, a former ONE title challenger and one of the sport’s most experienced names, presents a tough challenge. The bout has been announced as a title-contender fight, with the winner set to face the victor of the title unification clash between Superbon and Masaaki Noiri.
