Tyson Fury has issued a seven-day ultimatum for his promoters to make the huge heavyweight unification fight with Oleksandr Usyk.

Fury vs Usyk for all the heavyweight belts is the fight everyone wants to see next but the 34-year-old has said all parties involved, including Frank Warren and Bob Arum, must come up with the money before 1 September.

In a video in his Instagram page, he also stated the offer must be officially submitted to his lawyer, or else Fury will stay retired.

Speaking to his fans while out running, the WBC world heavyweight champion said: “Hi guys, for all those suitors out there who wanted to make the fight, I’m gonna give you all seven days – till the 1 September, to come up with the money.

“If not, thank you very much it’s been a blast. I’m retired. And also guys, forgot to say, all the offers submitted must be to my lawyer Robert Davies, in writing and with proof of funds. Let the games begin.”

“What a way to go out.”

He did recently relinquish the Ring magazine belt, which became vacant before Usyk claimed the vacant title on Saturday night in Jeddah, Saudi Arabia.

The Ukrainian did call out Fury and said he was sure he had not actually hung up his gloves for good.
