Meanwhile, Hearn was critical of whether the recent fight between Tyson Fury and Deontay Wilder would even go ahead, before going on to claim the bout – which is widely considered one of the greatest ever – would be boring.
Warren hit back at Hearn in an interview with The Times, even suggesting it is Hearn’s father, Barry, who runs the business – not the younger Eddie.
“I’ve never spoken to Eddie Hearn in my life,” Warren said, “but he annoyed me.
“He said the fight between Wilder and Fury would never happen; he said we had only sold 8,000 seats; he said it would be a boring fight.

“Wrong on all counts. Fake news.
“People need to hear this, and on the record. It’s Eddie Hearn’s father, Barry Hearn, who runs that business.
“The kid just goes off talking rubbish. He has an ego which is awful. If he was my kid, I’d slap him down.”
The 66-year-old watched on from ringside in Los Angeles as Fury was denied a win over Wilder in his WBC heavyweight title clash with the verdict coming back as a draw.
Nonetheless, Warren feels his man is the number one fighter in the division.
“Tyson is No 1 now, end of story,” Warren added. “It’s all changed. Joshua is under scrutiny now.
“The public won’t accept poor matches. He has become a corporate animal. Fury is the man of the people. He’s a boxing genius.”
