The Gypsy King confirmed that the scheduled April 29 fight date is a "worker" for him and is planning to begin an intense training camp as he bids to become the undisputed ruler of the heavyweight division.

In a video posted on social media, Fury said: "Hi guys, as fun as it's been over the last few days terrorising Usyk and his team, tomorrow I'm going to knuckle down into training camp, and I'll be doing a blackout as I always do on social media. Nav (Salimian) will be running my Instagram account, keeping you all updated on my training progress, and how everything is going.

"April 29 is definitely a worker, I will see you all on the night. Tune in, or be there or be square. This is the biggest event in British boxing history, the fight of the century. Two undefeated world heavyweight champions throwing down to see who is No 1 in the division: the undisputed world heavyweight championship on the line. Peace out, good training to Usyk, may the best man win."

The two camps have been trading barbs in recent days and Usyk's promoter Alexander Krassyuk had questioned Fury's desire to box on the April date.

He said: "The negotiations now go live on Instagram, so we see both fighters exchanging messages.

"We are expecting to get some basic agreement with the terms and things like that but it's still pending.

"We've been negotiating for so many months. We went through all the small issues, bigger issues, large issues whatever. So it's all done already. It's been done actually several weeks ago. But the one thing that was pending was Tyson's consent, which is still pending. Though he claims he's ready and pretends he's training. It doesn't look convincing but it's still the case."
