Musayev (18-3) has not fought since Rizin 20 in 2019 when he beat two opponents in a single night to win the promotion’s lightweight Grand Prix. He was subsequently involved in a dispute over pay but that has long since been resolved and the Azerbaijani fighter is currently in quarantine in Japan.
De Souza (11-1) is a BJJ black belt who is based permanently in Japan. He is coming off back to back stoppage wins at Rizin 22 and Rizin 27 and has also competed in submission grappling numerous times for the promotion, winning every time.
Also added to the card today was a featherweight fight pitting newly crowned champion Yutaka Saito (19-4-2) against promotional newcomer Vugar Keramov (15-3) in a non title bout. The latter hails from Azerbaijan and is already in quarantine in Japan.
In the heavyweight division Tsuyoshi Sudario (3-0) has been matched with Shoma Shibisai (6-2). The card will also feature a catchweight contest which is set for 73kgs and pits Satoshi Yamasu (11-6) against Bey Noah, a karate specialist making his MMA debut.
