Bob Arum is still planning to stage the clash between Tyson Fury and Dillian Whyte in Cardiff on March 26 despite the continued delay around negotiations.
Fury has been ordered to defend his WBC heavyweight title against domestic rival Whyte with the organisation ruling an 80 per cent purse split in the champion's favour.
Whyte has chosen to appeal the split and is locked in arbitration with the organisation which has led to purse bids being delayed for a second time.
