The card for Rizin FF’s next event has started to build, and it’s filled with former UFC fighters. The previously announced main event for the show, which takes place April 16 at Yokohama Arena in Yokohama, Japan, is between former UFC flyweight title challenger Kyoji Horiguchi (18-2) and Yuki Motoya (18-4). That fight, the promotion has announced, will take place at a 128-pound catch weight. Additionally, UFC vet Anthony Birchak (13-3) will move up a weight class to meet fellow UFC veteran and Japanese MMA legend Tatsuya Kawajiri (35-11-2) at featherweight. UFC vet Daron Cruickshank (18-9) will take on Japan’s Yusuke Yachi (16-6) at lightweight. UFC vet Heath Herring (28-15) returns at heavyweight to fight Olympic gold medalist Satoshi Ishii (14-7-1).
