Dillian Whyte has signed his contract to take on Tyson Fury for the WBC world heavyweight title after waiting until the final hours.
Whyte had until 6am today to put pen to paper on his huge clash with Fury per WBC rules after being named his mandatory challenger.
But on Monday evening it was still being reported that Whyte was yet to sign, with Fury taking to social media to call on him to ink the contract.
There were concerns that Whyte may not put pen to paper due to a dispute over the 80-20 purse split in Fury's favour.
But both Fury and Whyte have now signed contracts to ensure their all-British clash will go ahead with the fight expected to take place at Wembley on April 23.
Whyte holds the WBC interim title after beating Alexander Povetkin in a rematch and will finally get his shot at Fury's full world title.
The Londoner will earn £6million from the fight after signing the dotted line - plus a £3m bonus if he dethrones the unbeaten Fury.
Fury's co-promoters Frank Warren and Bob Arum won the purse bid with a record offer of £31m, of which Whyte is entitled to 20 per cent.
Warren and Arum then paid the WBC deposit of 10 per cent and issued the contract which Whyte had until 6am to sign.
Whyte himself has remained silent since the purse bid while Fury accused him of ducking the fight at the weekend.
Fury said: "I just heard that little sausage Dillian Whyte wants paying to turn up for a press conference. You little silly fat sausage, you’re getting that [a fist], you coward.

"Hi guys, just a quick one. I'm setting up a Just Giving page for Dillian Whyte so he can show up to the press conference and I'm going to donate first. My donation is 47p, you useless dosser."
Whilst the date and venue are not yet officially confirmed, Whyte previously told Sky Sports he was unconcerned about those factors.
Whyte said: "Wherever they want the fight, whenever they want the fight, I don't care.
"I've been trying to fight him for a long time. I've been ready to fight him for a long time.
"I just want to fight him for the world title now."
Eddie Hearn, who has been advising Whyte in the negotiations, recently denied a report claiming he had offered the fighter an alternative deal to remain on his DAZN platform.
Meanwhile, Anthony Joshua is set to rematch Oleksandr Usyk in a bid to win back his WBA, IBF and WBO world belts.
