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.

Despite the best efforts of those around them, heavyweights Oleksandr Usyk and Daniel Dubois refused to talk too much about the reason they are fighting again at this afternoon’s press conference in London.
