In what looks to be a first-time ever occurrence in a major MMA promotion, both a mother and her son will be competing on the same stage next month.
Rizin announced on Monday that Miyu Yamamoto, 41, a three-time world champion in women's freestyle wrestling, would make her MMA debut on their Sept. 25 show at the Saitama Super Arena.
Her son, Asen Yamamoto (0-1), 19, will face Kizaemon Saiga, on the same show. Yamamoto lost his pro debut on New Year's Eve's Rizin show to Kron Gracie, the son of Rickson Gracie. Asen Yamamoto was an age group wold champion at 17 under the name Asen Sasaki.
