Tyson Fury has told rival Dillian Whyte to sign the contract for their heavyweight title fight after verbally agreeing to the bout.
Fury's co-promoter, Frank Warren, outbid Eddie Hearn with a massive £31million bid to win the rights of the bout last week.
Whyte has refused to address the fight being announced since Warren won the bid, with Fury mocking the mandatory challenger for not speaking up.
