Chantelle Cameron becomes two-weight world champion as she dominates Michaela Kotaskova and calls for Mikaela Mayer next

Chantelle Cameron became a two-weight world champion as she secured the vacant WBO super-welterweight title with a unanimous decision victory over Michaela Kotaskova.

Immediately after the win on the Caroline Dubois vs Terri Harper undercard at London's Olympia, Cameron called for a fight with Mikaela Mayer and faced off with the American star, and fellow two-weight world champion, in the ring.

"So much respect for Mikaela Mayer, she's a great fighter, I wanted this fight with Mikaela for ages," Cameron told Sky Sports.

"We've been speaking, we should give the fans a great fight for women's boxing."

Cameron, a former undisputed world champion at 140lbs and the sole professional conqueror of Katie Taylor, was stepping up to super-welter for the first time and meeting Kotaskova in the first women's world title to be fought with three-minute rounds on UK soil.

She came into her own at that distance, winning a unanimous decision, 100-90 and 99-91 twice, after 10 three-minute rounds. Cameron didn't need to rush herself but applied solid, persistent pressure to her Czech opponent. Early on she found a home for a right over the top.

But it was her targeted work to the body that drained Kotaskova and forced the Czech to back away.

Cameron warmed to the task, reeling off uppercuts, slamming hooks into Kotaskova's stomach and then bombing more rights into the head.

Both picked up marks and bruises and Cameron was nicked on the nose. But Cameron was the fighter dishing out the hurtful punches and as the bout passed into its second half the Briton had Kotaskova reeling.

Kotaskova tagged Cameron occasionally, but she grew increasingly desperate, throwing out pattering punches to try to dissuade the former undisputed champ.

Cameron punched a left hook into Kotaskova in the eighth round to shake her up once more. But she didn't manage to chop her taller opponent down.

In the next session the Czech strode out into the centre of the ring to trade blows with Cameron. She took heart from that and came on again in the final round. Cameron covered up and uncorked a fine left hook, before seeing out her decision victory.

Irma Garcia crushed Emma Dolan's world title dream in three rounds to defend the IBF super-flyweight belt.

After winning the first British and Commonwealth women's super-flyweight titles, Dolan was challenging for world honours for the first time in her ninth professional fight.

Mexico's Garcia, vastly more experienced as a pro fighter, is not only a two-time world champion but a police officer (and qualified lawyer), as well as being 17 years Dolan's senior.

After the first round of action it looked like Dolan was handling the step up to world level. She got forward behind long straight punches and kept busy. Garcia even winced after taking a left hook to the head.

But Garcia changed everything in the second round. A hook with her southpaw left stunned Dolan and she knocked the Briton down.

A straight back hand, blasted down the middle, put Dolan over a second time. Bravely Dolan got through the round, but Garcia planted her back on the canvas in the third.

Then the Mexican bowled a right over. It caught Dolan on the forehead wobbling her. Dolan's corner pulled her out at that point, an expert call.

Courtenay: I want the Bridges fight

Former WBA bantamweight world champion Shannon Courtenay continued on the comeback trail, looking dangerous as she halted Sasha Booker in three rounds.

Courtenay selected single shots, nailing Booker flush with her backhand as well as clipping her taller opponent with the left hook. She dropped Booker in the second round, bringing power to bear. Courtenay kept the Nottingham fighter under pressure in the third. Their heads thumped together and Courtenay then sent Booker down with a left hook to the body.

Booker was counted out on a knee, clutching her head, with three seconds left in the round.

Courtenay is now hunting a rematch with Ebanie Bridhes, whom she beat in 2021 to win that WBA belt.

"I won a world title, world at my feet, lost it and everything came crashing down, I only had myself to blame," Courtenay said. "I want the Bridges fight."

Finnish prospect Teresa Makinen preserved her unbeaten record, coming through a tight eight-rounder with Chloe Watson.

The former European champion from Birkenhead landed sharp shots, catching Makinen with a right hook as they came out of a clinch. But Makinen managed to steer herself to a 77-75 victory.

Elizabeth Oshoba, Nigeria's 2022 Commonwealth Games medallist now based in Bristol, handed Chelsey Arnell a third-round stoppage defeat.

Oshoba lined up a brace of backhand shots, rocking Arnell and prompting the referee to step in and wave off the bout 42 seconds into the third.
