On Saturday's boxing double-header, Moses Itauma bids to become the second-youngest heavyweight world champion against Filip Hrgovic, while Mikaela Mayer and Chantelle Cameron meet in a major world title unification clash.
Briton Itauma, 21, is one of boxing's brightest young talents, with 14 wins and 12 knockouts. Hrgovic, 34, brings a 20-1 record and years of top-level experience, with his only defeat coming against Daniel Dubois.
Can Itauma take down Hrgovic at London's O2 Arena and win the vacant IBF title? Or will the Croatian's experience and power end the hype?
Meanwhile, Mayer and Briton Cameron collide in a three-belt light-middleweight unification fight at BP Pulse Arena in Birmingham. American Mayer holds the WBA and WBC titles, while Cameron owns the WBO belt.
The bout pits two top elite fighters against each other, with both aiming to move one step closer to becoming undisputed.
Here is all you need to know about Itauma v Hrgovic and Mayer v Cameron.

What information do we collect from this quiz? Can Itauma prove he is the real deal? Itauma has been earmarked for greatness since he was a teenager. He was sparring seasoned professionals while still at school.
Frank Warren took notice after seeing the schoolboy hold his own against one of his heavyweights and began sponsoring him before eventually signing him to Queensberry as a professional.
The 21-year-old has since lived up to the hype. His two biggest wins came against Dillian Whyte, who he stopped in the first round in August 2025, and Jermaine Franklin, who he knocked out in the fifth round in March.
Victory over Hrgovic would see Itauma become the second-youngest heavyweight world champion in history, behind Mike Tyson.
The IBF title became vacant after Oleksandr Usyk vacated his heavyweight belts, with the organisation initially ordering Itauma to face Cuban Frank Sanchez. Itauma had already agreed to fight Hrgovic, however, and Sanchez has accepted a step-aside deal that guarantees him a shot at the winner.
If Itauma can get through Hrgovic - an Olympic bronze medallist with a wealth of top-level experience - and then Sanchez, an all-British unification fight with either Daniel Dubois or Fabio Wardley could be on the horizon next year.
Dubois dethroned Wardley with an 11th-round stoppage in May to win the WBO title, with a rematch expected to take place in October.
Cameron was at the peak of her powers when she beat Katie Taylor by majority decision in Dublin in May 2023, handing the Irish superstar the first professional defeat of her career.
Taylor avenged that loss five months later, but Cameron's career subsequently stalled somewhat as she struggled to secure the biggest fights.
She has now reignited it under Most Valuable Promotions, co-owned by Jake Paul and Nakisa Bidarian, becoming a two-weight world champion when she beat Michaela Kotaskova for the vacant WBO light-middleweight title in April.
Now, Cameron, 22-1 (8 KOs), has the chance to prove she remains one of the very best fighters in the world against Mayer. The American, 22-2 (5 KOs), is a three-division world champion and is fighting for the first time under MVP.
The winner will hold three of the four major belts in the division, with Oshae Jones currently holding the IBF title. Cameron knows exactly what it takes to become undisputed, having unified the light-welterweight division in 2022.
Londoner Caroline Dubois is another British star who has flourished since joining MVP, beating Harper in April to become unified champion.
Dubois is now 13-0-1 (5 KOs), while American challenger Amelia Moore enters the fight unbeaten at 4-0 (1 KO).
Dubois is a heavy favourite and is targeting IBF champion Elif Nur Turhan and WBA champion Stephanie Han as she looks to complete the lightweight undisputed puzzle, while a budding rivalry with American Alycia Baumgardner could eventually produce a blockbuster showdown.
