Lennox Lewis will defend his world heavyweight title against Vitali Klitschko in April.
Ukrainian Klitschko told an US television show that all contracts for the bout had been signed and that they would fight on April 12th.
But both camps today insisted that the April 12th date remained only one of a number of possible options. That date remains the favoured one as it would ensure the bout took place in Las Vegas.
