Moses Itauma and Hamzah Sheeraz are among six fighters to have signed contract extensions with Queensberry Promotions.

Nick Ball and Anthony Cacace, two of Queensberry’s world champions, have also extended their commitment to the promoter. Liam Davies and Sam Noakes are the two others.

Itauma, 19, is widely regarded as the world’s most promising young heavyweight. He fights Demsey McKean on the undercard of Oleksandr Usyk-Tyson Fury II at the Kingdom Arena in Riyadh, Saudi Arabia on December 21.

The 25-year-old Sheeraz is similarly considered the middleweight with the greatest potential, as he most recently again demonstrated in September when stopping Tyler Denny.

“I am thrilled to secure the futures of such richly talented fighters,” said Queensberry’s Frank Warren. “We have worked with nearly all of them right from the beginning or very early in their careers and the faith we have shown in each other has been rewarded by them realising their potential and justifying the belief we had in them.

“That Nick Ball, Anto Cacace and Liam Davies have reached world-title status is a particular joy, and the good news is that I am certain there are more world champions to come from this group, who are all set for further exciting developments in the coming months.”

The WBA featherweight champion Ball, 27, earlier in October made the first defence of his title when he defeated Ronny Rios in Liverpool. Cacace, 35 and the IBF super-featherweight champion, in September defeated Josh Warrington.

On Saturday at Birmingham’s Resorts World Arena the super bantamweight Davies, 28, fights Shabaz Masoud. 

The 27-year-old Noakes, who like Itauma is managed by Warren’s son Francis, is the British, Commonwealth and European lightweight champion.
