Disgraced British heavyweight Dereck Chisora has launched an appeal against the decision to revoke his licence following his brawl with David Haye, promoter Frank Warren confirmed on Thursday. Chisora's licence was withdrawn "indefinitely" by the British Boxing Board of Control (BBBC) following his fight with Haye at a press conference following his WBC title bout with Vitali Klitschko in Germany. However Warren has confirmed that Chisora is to mount a bid to regain his licence, and said he believes a grudge match against Haye is now inevitable. "It's a natural fight, it doesn't matter what anyone says," Warren said. "It's a bigger fight than either of them fighting Wladimir or Vitali Klitschko. "There's lot for them to fight about - in a proper environment." Warren said Chisora was appealing his ban on the basis he had not received a fair hearing by British boxing chiefs. "The appeal has gone in already. The grounds for the appeal are that we're not satisfied with the way the hearing went," he said. "There was also no chance to review any evidence before the hearing. All I want to see is a fair hearing. "Dereck Chisora will present his side of events and then we'll see what happens.
