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”.
