Daniel Dubois’ trainer has accused Oleksandr Usyk of conning the referee the first time the two heavyweights squared off.

Daniel Dubois' trainer tells Oleksandr Usyk he "conned the boxing world" as the two champions meet in London before this summer's undisputed title fight.

Oleksandr Usyk shrugged off accusations of cheating and fakery and said he was ready to become the undisputed heavyweight champion of the world for a second time when he fights Daniel Dubois at Wembley Stadium on July 19.
