Two championship belts will be on the line when RIZIN returns to Saitama Super Arena on Sept. 29, the promotion announced Sunday.
Lightweight king Roberto Satoshi defends his 155-pound title for the first time since April 17, 2022, when he faces Brazilian knockout artist Luiz Gustavo in the main event of RIZIN 48 in Saitama, Japan. In the co-main event, Naoki Inoue battles Soo Chul Kim for the bantamweight title Kai Asakura recently vacated to sign with the UFC.
