Undisputed: Naoya Inoue was made to work for his late-round stoppage of Paul Butler
(Picture: AP)Naoya Inoue stopped Britain’s Paul Butler late to make history as the first undisputed men’s bantamweight world champion of boxing’s four-belt era in Tokyo on Tuesday.
‘The Monster’ is the first Asian boxer ever to become a four-belt world champion after a completely dominant display at Ariake Arena that saw him produce a typically spiteful 11th-round knockout to add the WBO belt to his WBA, WBC and IBF titles in what will surely be his final fight at 118lbs before moving up in weight once more.
