Naoya Inoue will look to become a four-division world champion on Tuesday, as the Japanese superstar challenges Stephen Fulton for his unified super-bantamweight titles. Inoue, 30, is Indy Sport’s pound-for-pound No 1. The “Monster” is a former light-flyweight champion, a former unified super-flyweight champion, and he recently vacated his undisputed bantamweight belts to move up to super-bantamweight. Fulton, 29, is unbeaten like his opponent here, and the American will carry the WBC and WBO titles into Tokyo this week, where Inoue awaits. Last time out, Inoue toyed with Paul Butler in December before finishing the Briton to achieve undisputed status at bantamweight. Meanwhile, Fulton last fought in June, outpointing David Roman to retain his super-bantamweight belts. Here’s all you need to know. When is it?
