Frank Warren does not believe Tyson Fury will ever stop his foul-mouthed rants after the heavyweight was warned he faces disciplinary action from the British Boxing Board of Control next month.
Fury was set to face Chisora in a rematch for the European and British heavyweight titles in what would have also been an eliminator for the WBO world title belt, held by Wladimir Klitschko, in Manchester on Saturday. However, Chisora pulled out of the fight on Monday evening, after scans confirmed he had fractured his hand in a sparring session. Fury is still set to attend a disciplinary hearing on August 13 to answer a misconduct charge after he erupted into an expletive-filled attack on Chisora, Klitschko and British rival David Haye at a public press conference last week.
Chisora, who was banned after he brawled with Haye at a press conference in 2012, even apologised for Fury's profanities. Fury has been fined by the Board before for comments made on Twitter but Warren is not convinced fining him again will make him change his ways.
"You've seen his rants and raves on the internet and they are what they are, I've no idea why he does it," Warren had told ESPN before Chisora pulled out. "It's a shame. I just think that's his way of expressing himself. Maybe that's how he talks in general.
"Dereck has changed his ways and he has done well in the last couple of years. Some of the things Tyson says on Twitter are quite funny but I think a lot of it is because he gets caught up in the moment which is a shame.
"I don't want to hear guys do that but you are never going to change this fella, he is what he is. I've promoted him for one fight previously but this is how he is, he's done it before."
Warren had been confident that the winner between Fury and Chisora would face world No.1 Wladimir Klitschko early next year.
Those plans may now have been shelved for the time being with Saturday's fight postponed. Fury, who out-pointed Chisora in 2011, has compiled a 22-fight unbeaten record but his momentum stalled last year after Haye twice pulled out of fights against him with injuries.
