RIZIN 15 live from the Yokohama Arena in Yokohama, Japan. The promotion returns to Yokohama for the first time in two years with many of the biggest stars in the promotion. The inaugural Rizin light heavyweight title will be on the line when 2015 RIZIN Heavyweight GP winner King Mo meets the man he defeated to win the grand prix, Jiří Procházka. In the night’s co-headliner, RIZIN bantamweight champion Kyoji Horiguchi takes on former UFC flyweight Ben Nguyen. Since leaving the UFC with a 7-1 record, Horiguchi has won eight straight fights, including stoppages over Bellator champ Darrion Caldwell, former consensus No. 1 flyweight Ian McCall, and former King of Pancrase Shintaro Ishiwatari.
