Rizin 31 is already upon us this weekend. The show will take place at the Pia Arena MM in Yokohama on Saturday for those on the east coast. The show will be headlined by 11 fights. Nine fights will be MMA rules and two will be kickboxing. Some of the notable fights include Yutaka Saito defending his Rizin featherweight championship for the first time, the return of Kanna Asakura, a big boy heavyweight match, and more. We will look at a few of the fights on the card and break down said fights.
