Dubois

World championship boxing returned to the historic Kensington venue for the first time in decades. The Olympia had previously staged headline fights involving stars such as Chris Eubank Jr and Prince Naseem Hamed.

Harper strode towards the centre of the 19th-Century grand hall, buoyed by her travelling Yorkshire faithful.

Dubois, who once pretended to be a boy named Colin so she could be allowed to box, also received a warm reception as she entered to “I’m Every Woman” by Whitney Houston.

The fight had been a long time coming, and the rivalry had grown increasingly tense in the build-up. Dubois repeatedly questioned Harper’s achievements and credentials, while Harper shoved Dubois during a fiery media face-off earlier in the week.

By the halfway stage, however, the contest had not quite lived up to the hype, with Dubois edging the rounds through steady work to the body.

Then, suddenly, the fight came alive. Dubois set up a knockdown with a sharp double jab followed by a left hook, sending Harper to the canvas.

Harper rose to her feet as Dubois leapt in celebration, prompting the referee to warn her for failing to return to her corner.

Dubois increased the pressure. She landed thudding southpaw left hands in the seventh and eighth as blood began to drip from a cut on the inside of ‘Belter’ Harper’s left eye.

Watching from ringside was pound-for-pound star Claressa Shields, shouting encouragement for Dubois.

A strong combination from Dubois in the ninth suggested a stoppage might be imminent, but Harper rallied to land shots to Dubois’ head in the 10th and final round.

“Terri is very tricky; she navigated herself very well and it was up to me to push the pace,” Dubois told BBC Radio 5 Live.

“She is a champion and she doesn’t like to lose, but neither do I.

“The better woman won tonight and I hope she can give me my respect.”

Shane McGuigan – Dubois’ trainer:

“Anything can happen in a boxing match. It depends how Harper approaches the fight. If she comes out and genuinely tries to win the fight, she will walk on to something. If she goes super negative, it will go a bit later. But I do think Caroline will stop her.”

Prediction – Dubois

Mikaela Mayer – American three-weight world champion:

“I think Harper is a good boxer. You know she’s going to work hard, will do her best and always puts on fights that everyone wants to see.

“She’s challenged herself against some top names so you have to respect her for that. But I don’t know if she has the pedigree to beat Dubois, who has an extensive amateur career and is a very technically sound boxer.

“So if I had to put my money on it, I’d put it on a Dubois win but either way, it’s going to be a great fight and I’m looking forward to it.”

Prediction – Dubois

Shannon Courtenay – bantamweight boxer:

“It comes down to discipline under pressure. The fighter who controls the tempo and doesn’t get emotional will win.”

Prediction – 50/50

Paul Smith – coach and retired boxer:

“I think Dubois wins this one by late stoppage.”

Prediction – Dubois

The undercard for Sunday’s London show is stacked with four female world-title fights featuring British fighters, all of whom made weight successfully.

Londoner Ellie Scotney, 28, has the chance to become Britain’s youngest ever undisputed champion – male or female – in the four-belt era when she faces Mexico’s Mayelli Flores for the undisputed super-bantamweight title.

Both fighters came in under the 8 st 9 lb limit, with Scotney towering over the 4 ft 11 in Flores by five inches at the face-off.

Flores vowed to bring “war to the ring,” citing Mexican legends Julio Cesar Chavez Sr and Saul ‘Canelo’ Alvarez, while Scotney responded: “I’m more than ready. All the belts, all the marbles.”

Northampton’s Chantelle Cameron weighed in for her WBO light-middleweight world-title challenge against unbeaten Czech fighter Michaela Kotaskova.

The fight will feature three-minute rounds, longer than the usual two in women’s boxing, and a win could set up a bout with three-division champion Mikaela Mayer, who was ringside.

“I’ve been working hard in the gym, getting ready for the three-minute rounds. I’ve got the engine,” said the 34-year-old Cameron.

Norwich’s Emma Dolan, 27, aims to claim her first world title against IBF super-flyweight champion Irma Garcia.

Dolan, unbeaten in eight fights, will face the experienced 44-year-old Mexican, who has had 35 professional bouts. Dolan promised she will “go in there and take over”.
