By Scott Gilfoid: Tony Bellew says he’s going to immediately call out WBC/WBO cruiserweight champion Oleksandr Usyk (14-0, 11 KOs) if/when he wins the World Boxing Super Series [WBSS] tournament on May 11th in his fight against IBF cruiserweight champion Murat Gassiev (26-0, 19 KOs). Bellew says if he lands his left hook on Usyk, it’ll have some kind of an effect.
