When Matchroom Boxing promoter Eddie Hearn announced on Friday that welterweight titleholder Kell Brook would move up two weight classes to challenge the fearsome Gennady Golovkin for his middleweight belts, he also promised to give fans “a packed show with multiple world-title fights and some of the biggest names in British boxing.”

Hearn began to deliver on Monday, announcing that flyweight world titleholder Johnriel Casimero will defend his belt against Charlie Edwards on the card, which will take place Sept. 10 (HBO in the United States, Sky Box Office in the United Kingdom) at the O2 Arena in London.

A former junior flyweight world titleholder, Casimero (22-3, 14 KOs), 26, of the Philippines, moved up in weight and traveled to Thailand to challenge Amnat Ruenroeng, who beat him by unanimous decision 13 months ago.

They met in a rematch on May 25 in China and Casimero knocked out Ruenroeng in the fourth round to claim the 112-pound belt. Casimero will be making his first title defense against England’s Edwards, 23, who is inexperienced as a professional but was one of the Great Britain’s top recent amateurs.

Edwards (7-0, 3 KOs) turned pro in January 2015 and will be taking a tremendous step up in class of opponent.

“Many people may think this is too early, but believe me when I say this: That IBF world title is coming home with me,” Edwards said.

“People underestimate my engine. Halfway through the fight, when he’s behind, he will not be catching up. I didn’t turn pro to knock over journeymen. I’m in this game to take over the lighter weight divisions. The team behind me know I am more than ready for this and I would like to thank them, Eddie and Barry Hearn for giving me this chance. I won’t let anybody down.”

In a tuneup fight for his title shot, Edwards will be in action on Saturday in Berlin, where he will face Jose Aguilar (16-25-4, 6 KOs), 31, of Spain, in a scheduled six-round bout on the undercard of super middleweight titlist Giovanni De Carolis’ defense against Tyron Zeuge.

“This is a huge gamble for Charlie at this stage in his career, but him and the team feel very confident they can beat Casimero,” Eddie Hearn said. “At flyweight, there is only so much experience you can gain, and this is a huge opportunity for him to become world champion on home soil in what will be just his ninth fight.

“Sept. 10 is the biggest night in world boxing so far in 2016, and I’m delighted to provide this opportunity for Charlie. I believe Britain will have yet another world champion that night.”
