Williams agrees new contract

Frank Warren has finally agreed terms to extend the contract of his British heavyweight champion Danny Williams.

Warren returned from a trip abroad last week to discover that Williams, who has lost just once in 24 fights, had still to put pen to paper.

Following yesterday's signing, Williams will challenge for the vacant World Boxing Union heavyweight title against the veteran fighter Tim Witherspoon in Denmark on 13 October if Mike Tyson fights on the same night against Denmark's Brian Nielsen. However, Tyson has an alternative offer from Don King to consider. "I'm glad it is all over,'' Warren said. "There have been so many outside influences promising Danny so much but he has seen that my offer is the best.''

Williams last fought in July, retaining his British and Commonwealth titles by knocking out Julius Francis, but in the days before the fight it was rumoured and then revealed that the BBC had made him an offer. The BBC had planned to add Williams to their scheduled Saturday night fights.
