Cameron–Mayer II: Junior Middleweight Rematch Set for Dubai

Chantelle Cameron and Mikaela Mayer are wasting no time. The rivalry goes straight back into the fire.

Their junior middleweight rematch is officially signed and will serve as the co-main event on the Jake Paul vs Cédric Doumbé show on December 24 in Dubai, a swift return after Cameron edged a decision in August to unify world titles at 154 pounds.

This time, the stakes feel heavier.

Cameron walks into the ring as the unified champion at junior middleweight, holding the WBO and WBC belts after that first tight encounter. Her record — 23 wins, 1 defeat, 8 knockouts — underlines a career built on pressure, volume, and stubborn refusal to back up.

Mayer, though, has refused to treat that loss as anything other than a starting point. The American, now 22-3 with 5 stoppages, has been blunt about her own performance in August, admitting she fell short of her ceiling and needed to reset. She has spent the months since dissecting the mistakes, tuning the details, and promising a very different version of herself in Dubai.

“Mayer vs. Cameron was a great fight that I truly hope everyone enjoyed,” Mayer said. “Although I don't feel I performed to my highest potential, I've been working hard to fix the mistakes I made and I will 100% come back stronger! I'm taking my belts back on Thursday, Dec. 24th.”

The message is clear: she sees this not as a second chance, but as a correction.

The first bout came in Cameron’s backyard, with all the subtle advantages that brings — familiar surroundings, home support, and the comfort of routine. Mayer’s camp believe that getting Cameron on neutral territory in Dubai could tilt some of those fine margins the other way. At this level, the edges are razor-thin. Venue matters. So does psychology.

Nakisa Bidarian of MVP highlighted what this immediate return says about both women: neither asked for a soft touch, a tune-up, or time to rebuild. They went straight back to each other. It is the choice of fighters who see themselves at the top of the sport and intend to stay there.

For Cameron, the assignment is simple but brutal: prove August was no debate, lock down her status at 154, and turn a close rivalry into a clear hierarchy.

For Mayer, it is something else entirely. It is about erasing the doubts, ripping back the belts she believes should have been hers, and doing it under brighter lights, in a city far from Cameron’s home comforts.

On a card built for spectacle in Dubai, this is the fight that could decide who truly rules at junior middleweight — and which of them walks into 2025 as the division’s defining force.
