Tyson Fury is in training camp ahead of his undisputed clash against Oleksandr

Boxing fans are worried for Tyson Fury after training footage emerged online ahead of his blockbuster fight against Oleksandr Usyk.

Fury meets Usyk in a big undisputed showdown on May 18 following the postponement of their February clash.

The WBC, WBA (super), WBO and IBF world heavyweight titles will be on the line when the two heavyweight stars collide in Riyadh, Saudi Arabia.

Fury is back in training camp after a nasty cut forced him to withdraw last month.

Footage of the self-proclaimed ‘Gypsy King’ in preparation for his fight against Usyk has surfaced online.

And fight fans are concerned for the unbeaten British star, who went through his paces in a strength and conditioning session. Check it out below:

The clip shows him on sled pushes and performing squats, leaving people on social media unimpressed.

One X user wrote: “Oh crap he looks awful. Please let him beat Usyk.”

A second tweeted: “That is genuinely some of the least impressive jumping up and down I’ve ever seen.”

A third added: “He looks like it’s first ever time in a gym every time.”

Another commented: “He jumps up and down like a toddler.”

Fury hasn’t fought since his underwhelming victory over former UFC champion Francis Ngannou last October.

He beat Dereck Chisora in the last defence of his WBC title as he looks collect the other three belts in the division.

If he beats Usyk, then an all-British showdown against Anthony Joshua could be next.

Joshua brutally stopped Ngannou earlier this month, but his victory didn’t impress Fury.

“I’m still dismissive of him,” he said. “AJ’s made to measure for me. Just because he knocked out Francis Ngannou – it’s not the same. He couldn’t land any of those rights on Usyk, a way smaller and lighter man. Styles make fights and his style is made for me.”
