Frank Warren has slammed his promotional rival, Eddie Hearn of Matchroom.
There is no love between the two UK promoters, and there is no shortage of words being exchange in recent years.
Their respective companies will go head to head on December 22 - when Warren's company stages Carl Frampton vs. Josh Warrington on BT Sport Pay-Per-View and ESPN+, while Hearn stages the Dillian Whyte-Dereck Chisora rematch on Sky Sports Box Office and DAZN.
According to Warren, Hearn is fooling everyone in the boxing business. He says Hearn's father, Barry Hearn, is the actual individual who runs and operates the boxing brand of Matchroom.
But Warren's anger is more geared to some of Hearn's statements in the last few months in connection to the heavyweight bout between Deontay Wilder and Tyson Fury.
“I’ve never spoken to Eddie Hearn in my life, but he annoyed me," Warren said to The Times.
“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.”
Fury fought Wilder to a controversial twelve round split draw at Staples Center in Los Angeles. Many observers believe Fury had done enough to walk away with the win - and Warren certainly agrees.
“Tyson is No 1 now, end of story,” Warren added. “It’s all changed. [Anthony] 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.”
