Tyson Fury has sent a clear message to Dillian Whyte ahead of their upcoming fight.
The two are finally set to meet in the ring on April 23 at Wembley Stadium, with Fury defending his WBC championship. However, the fight currently hangs in the balance as Whyte has not yet signed his contract for the bout and has only a matter of hours to do so.
The fight has already has encountered numerous delays, with purse bids being pushed back on four occasions but an agreement was finally reached earlier this month.
Since then though, Whyte has gone quiet - and he now must sign the contract by 6am on Tuesday or could lose the opportunity to face Fury.
Fury signed the contract over two weeks ago but Whyte is yet not put pen to paper. If he doesn't do so, WBC's rules state that Fury can look elsewhere.
Fury said: "Today's the final day to sign the contract you big dosser. So get it signed, s***house or move on. Jog on you muppet, come on son. Get out the way, stiff a***."
Whyte is set to earn by far the biggest payday of his career, banking £6m from the fight plus a handsome £3m bonus should be beat Fury.
Fury's camp have been irritated by Whyte in the build-up, accusing him of not promoting the fight at all and refusing to give an update since talks progressed in January.
Whyte's promoter Eddie Hearn lost the purse bids for the fight, with Fury's promoters Warren and Bob Arum taking the lead.
Whyte is coming off the back of a win over Alexander Povetkin, avenging his KO defeat to the Russian in 2020, with Fury fighting for the first time in the UK since his trilogy contests with Deontay Wilder.
