Mikaela Mayer vs Chantelle Cameron: Weigh-In Tensions Explode

Mikaela Mayer and Chantelle Cameron had promised respect all week. At the final weigh-in in Birmingham, respect went out the window.

The two champions met centre stage, foreheads jammed together, eyes locked. Neither moved. Then the words started. Within seconds, security were between them as a simmering rivalry finally boiled over on the eve of one of the biggest fights in women’s boxing.

“I’m gonna smash her f****** head in now,” snarled Cameron, dragged away but still spitting fire.

So much for the polite build-up.

Respect turns into raw edge

Until Friday, this matchup had been sold on pedigree, not poison. Mayer, the American stylist with a 22-2 (5 KOs) record and belts from the WBA and WBC at super-welterweight. Cameron, 22-1 (8 KOs), the WBO champion, the only woman to have beaten Katie Taylor in the Irish icon’s professional career.

They had spent the week talking about legacy, about levels, about how easy it had been to make the fight. No cheap shots, no fake animosity. Two elite operators, three-weight world champion Mayer and two-weight world champion Cameron, treating it like business.

Then they touched heads.

Cameron, weighing in at 147.6lbs for just her second fight at super-welterweight after April’s win over Michaela Kotaskova, clearly didn’t like what she heard up close. Mayer, who came in at 148lbs – three pounds lighter than in her October 2025 win over Mary Spencer – insisted she’d said nothing to spark it.

“You’re deluded. Shut your mouth, you are so deluded,” Mayer snapped back as Cameron raged. “I didn’t say a word, you are making things up because you don’t believe in yourself. You’re going to get humbled.”

The veneer of civility cracked. The fight suddenly felt personal.

Mayer welcomes the fire

Nobody had really seen this version of Cameron in the build-up. Maybe not even Mayer.

“She said I’m too slow, but there is no way Chantelle Cameron is faster than me,” Mayer said, almost amused by the sudden nastiness. “I didn’t know this Chantelle Cameron existed, I like it.”

It was a telling line. Mayer, the technician, has built her career on control – of distance, of tempo, of emotion. Cameron, who has made her name as a relentless pressure fighter, now brings raw fury into the ring with her titles.

The clash of styles was already compelling. Now it has an edge you can feel.

Dubois and Moore light the fuse again

The fireworks weren’t limited to the main event.

Caroline Dubois and Amelia Moore reignited their own feud with another heated face-off, trading insults as if points were already on the cards. Dubois, the WBC and WBO lightweight world champion, hit 134.8lbs and stared straight through her American challenger.

“She knows I’m coming to take her head off. Welcome to my world,” Dubois warned, voice cold, not raised.

Moore, 4-0 as a professional and just a shade lighter at 134.4lbs, refused to play the underdog.

“This is my world. I’ve been waiting my whole life for this point, my whole life,” she fired back.

Dubois stands on the brink of something bigger. Win here and the noise around a clash with Alycia Baumgardner will only grow. Baumgardner, the WBO, WBA and IBF super featherweight world champion, is stepping into Dubois’ division to face Elif Nur Turhan on November 8. If both come through, the collision course writes itself.

Harper, Reyes and a familiar path

Further down the card, the storylines keep looping back to Dubois.

Terri Harper, returning for the first time since her defeat to Dubois in April, weighed in at 137.8lbs. She faces Houston’s Miranda Reyes, another fighter who knows exactly how hard Dubois hits. Reyes, who came in at 136.6lbs, has already shared the ring with the Londoner and will measure Harper against that experience.

At featherweight, Coventry’s Jessica Barry registered 125.6lbs ahead of her bout with America’s Reina Tellez, who matched the same weight. Tellez has already earned a reputation for saying yes when others hesitate, famously stepping in to fight Amanda Serrano on just 15 days’ notice earlier this year. She doesn’t rattle easily.

Tysie Gallagher, at 121.6lbs, will make her debut under the MVP banner against Chicago’s Brandi Robinson, also 121.6lbs, in a matchup that could quietly steal some attention if the action lives up to the intent on stage.

A card crackling with tension

What began as a card built on quality now crackles with needle.

Mayer vs Cameron was always a meeting of champions, a clash of eras and styles. After that weigh-in, it feels like something else entirely. Pride is on the line. So is status at the very top of women’s boxing.

The talking is done. On Saturday night in Birmingham, somebody gets humbled.
