Mikaela Mayer vs Chantelle Cameron: A Grudge Match Unfolds

Mikaela Mayer and Chantelle Cameron had spent the week selling respect. On Friday in Birmingham, that veneer ripped away in seconds.

The final weigh-in for their super-welterweight world title showdown detonated into a genuine grudge. No scripted snarling. No half-hearted shoves. This was raw.

They stepped in, forehead to forehead, neither woman blinking. The words came first, then the fury. Security dived in as Cameron, usually the quieter of the two, erupted.

“I’m gonna smash her f****** head in now,” she snapped, eyes fixed on Mayer.

The room shifted. The fight suddenly felt different.

Respect goes out the window

Until that moment, the build-up had been almost old-fashioned. Two elite champions talking about legacy, weight cuts, gameplans. No cheap shots. No circus.

Then Mayer, the American holding the WBA and WBC belts, came in at 148lbs – three pounds lighter than in her last outing against Mary Spencer in October 2025. WBO champion Cameron, in just her second fight at super-welterweight after beating Michaela Kotaskova in April, followed at 147.6lbs.

Numbers done. Formalities over. That was supposed to be it.

Instead, something said in that tight, tense clinch of a staredown lit the fuse. Cameron bristled.

“She isn't intimating me, all that yapping, getting in my face, watch now, watch tomorrow,” she fired back on stage. “You're deluded. Shut your mouth, you are so deluded. 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 switch had flipped. The usually reserved technician from Northampton sounded like a fighter who had been waiting months to let this out.

Nobody saw this coming. Perhaps not even Mayer.

Mayer welcomes the fire

Mayer, a three-weight world champion and one of the most polished operators in women’s boxing, had spent the week leaning on her resume and experience. On Friday, she leaned into the chaos.

“She said I'm too slow, but there is no way Chantelle Cameron is faster than me,” she said, almost amused by what she was seeing. “I didn't know this Chantelle Cameron existed, I like it.”

This is what makes Saturday night so compelling. Mayer, the decorated American technician. Cameron, the only woman to beat Katie Taylor in the Irish icon’s professional career. Two champions, two proven big-fight performers, now fuelled by something sharper than mutual respect.

One of the most high-profile fights in women’s boxing just found its edge.

Dubois and Moore light the fuse again

The fireworks didn’t stop with the main event.

Caroline Dubois and Amelia Moore picked up their own feud exactly where they left it, trading insults with the ease of seasoned rivals. The tension between them has been simmering for weeks; at the final face-off, it almost boiled over again.

Dubois, the WBC and WBO lightweight world champion, hit the scales at 134.8lbs. She stared down Moore and delivered a final warning.

“She knows I'm coming to take her head off. Welcome to my world,” Dubois said, voice flat, message clear.

Moore, unbeaten at 4-0 and unfazed, snapped straight back. “This is my world. I've been waiting my whole life for this point, my whole life.”

She weighed in at 134.4lbs, fractionally lighter, but gave away nothing in conviction. For her, this is the night she steps out of the shadows. For Dubois, it is another chance to prove she is the new standard at lightweight.

Lurking in the background is Alycia Baumgardner. The WBO, WBA and IBF super featherweight world champion is stepping into Dubois’ division to face Elif Nur Turhan on November 8. If Dubois comes through Moore, the path to a blockbuster with Baumgardner starts to look very real.

Stacked undercard, serious jeopardy

Beneath the headline drama, the card is loaded with stories of its own.

Terri Harper returns for the first time since her defeat to Dubois in April. She came in at 137.8lbs, looking to reset her career against Miranda Reyes, another fighter who knows Dubois’ power up close. Reyes, from Houston, weighed in at 136.6lbs and will not be here to make up the numbers.

Coventry’s Jessica Barry, fighting close to home, registered 125.6lbs ahead of her meeting with Reina Tellez, who matched the same weight. Tellez made headlines earlier this year when she stepped in to fight Amanda Serrano on just 15 days’ notice. She will not be intimidated by the occasion.

Then there is Tysie Gallagher, stepping into a new chapter under the MVP banner. She hit 121.6lbs, as did Chicago’s Brandi Robinson. For Gallagher, it is a debut with a powerful promotional machine behind her. For Robinson, it is a chance to spoil the script.

Birmingham has seen big nights before. This one carries something extra. A card stacked with champions, contenders and comeback stories – and a main event that has turned from polite showcase into something far more personal.

On Saturday, when Mayer and Cameron touch gloves, will that flash of hatred linger, or will it vanish the moment the first bell rings?
