Anthony Joshua could retire with a "disappointing career" if he loses to Oleksandr Usyk again on Saturday night, according to Kell Brook.
The former welterweight world champion, who announced his own retirement earlier this year after beating Amir Khan in February, believes Joshua losing a second consecutive fight would be a disaster for the Brit. And he feels that if the bout doesn't go his way, he could hang up the gloves with a record many will feel is lacklustre.
Joshua has beaten a number of major names during his career, including Wladimir Klitschko, Andy Ruiz Jr and Joseph Parker. But he has lost on the big stage as well, first to Ruiz in the summer of 2019 and then last September against Usyk in a disappointing showing at Tottenham Hotspur Stadium in London.
