Anthony Joshua has been warned he will lose to one of Britain’s rising heavyweight stars.
Promoter Frank Warren reckons the winner of Daniel Dubois against Nathan Gorman will topple Joshua whether he beats Andy Ruiz Jnr in a rematch or not.
Dubois takes on fellow heavyweight prospect Gorman for the British title at the O2 a week on Saturday.
The pair have just 27 fights between them – all wins – but Warren believes whoever has their hand raised next week would be ready to face former WBA, IBF and WBO champion Joshua.
It has been claimed that Dubois, now 21, knocked out Joshua in sparring three years ago while Gorman has a similar style to Ruiz Jnr.
Warren said: "I really do think the winner would beat Joshua.
"We see how he struggles with fast hands, small men – that is Gorman – and Dubois has already knocked him out in sparring with big gloves on at 18 years of age.
"They are two exceptional young talents. They both have the desire that they will move on and do great things."
Meanwhile, Warren says he has no problem putting Tyson Fury in with drugs cheat Jarrell Miller if the American can get a licence.
Fury is looking for an American opponent for his October 5 date at Madison Square Garden in New York.
Miller failed three drug tests for Endurobol, EPO and Human Growth Hormone in the lead up to a fight with Joshua that was cancelled.
Warren added: "I don’t police the sport so if someone has a licence then I will use their services."
