Boxing: Chisora appeals loss of licence Heavyweight fighter Dereck Chisora has appealed against the withdrawal of his British boxing licence, the promoter Frank Warren said yesterday. "The appeal has gone in already," Warren said. The grounds for the appeal are that we're not satisfied with the way the hearing went. The British Boxing Board of Control withdrew Chisora's licence this month after he was involved in a post-fight brawl with retired former world champion David Haye in Munich in February. The Zimbabwe-born fighter was declared "not a fit and proper person to hold a licence." He had already been banned indefinitely by the World Boxing Council for a separate incident.
