Fury set out an ambitious five-fight plan, including a long-awaited bout against Joshua.

WBC champion Fury’s unification bout with Usyk, who holds the WBO, WBA and IBF belts, had been due to take place in Riyadh later this month.

However, the eagerly anticipated contest was postponed until May 18 in Saudi Arabia after the British fighter suffered a deep cut above his eye in training.

Fury expects to have a rematch with Ukraine’s Usyk regardless of the outcome of their first fight, before facing former world heavyweight champion Joshua in one or two bouts and then Francis Ngannou, whom he beat in October.

“I keep hearing talk of people saying I should retire or I’m going to retire soon or whatever,” Fury said on his Instagram feed on Thursday, showing stitches on the cut above his eye.

“I ain’t retiring. I’ve got two fights with Usyk for the undisputed, twice. Then I’m going to fight AJ (Joshua) at least once, maybe twice, if there’s a rematch — if he wants one after the first battering I give him.

“Then I’m going to fight Ngannou again. That’s just the start. There’s five fights for you to whet your appetite. I ain’t going nowhere. I’m 35 years old and in the prime of my life.”

Fury has won 34 fights with one draw since turning professional in 2008.

His most recent fight was a controversial victory over former UFC mixed martial arts champion Ngannou, who made his professional boxing debut. Fury was knocked down by the Cameroonian but won through split decision.

Two-time former world champion Joshua is set for a non-title fight with Ngannou, also in Saudi Arabia, March 8.
