LONDON, July 17 (Reuters) – Anthony Joshua’s return against Ihor Prenga is no longer the only headline. Two world champions, Hamzah Sheeraz and Josh Kelly, will defend their titles on the same card. The undercard has become the main attraction for UK boxing’s next generation.
Sheeraz, the WBO middleweight champion, faces Germany’s Simon Zachenhuber. Kelly, the WBA welterweight champion, meets Caoimhin Agyarko. Both fights are title defenses. Both are high-risk.
Sheeraz vs Zachenhuber: A Title Defense with High Stakes
Sheeraz, 27, holds a 21-0 record with 17 knockouts. He has not gone the distance since 2022. Zachenhuber, 30, is 24-1 with 15 KOs. His only loss came via split decision in 2024. The German is a legitimate threat.
Sheeraz’s rise has been rapid. He won the WBO belt in March 2026 by stopping Liam Williams in the eighth round. A win here solidifies his claim as the division’s top young star. A loss derails everything. The stakes are binary.
Kelly vs Agyarko: World Champion Meets Ambitious Challenger
Kelly, 32, is 16-1-1 with 8 KOs. He has held the WBA welterweight title since 2025. Agyarko, 28, is 19-0 with 11 KOs. He has never lost. The challenger is hungry.
Agyarko earned this shot by stopping former champion Kerman Lejarraga in February. His style is aggressive. He pressures. He does not take a backward step. Kelly is a slick boxer. The clash of styles is compelling.
The New Wave: Redefining UK Boxing
Sheeraz and Kelly represent a shift. UK boxing has long relied on Joshua, Tyson Fury, and Oleksandr Usyk. Now a new tier is emerging. Matchroom promoter Eddie Hearn told BBC Sport: “These two are the future. They are world champions who can sell out arenas on their own.”
Both fighters have strong fan bases. Sheeraz draws from London’s East End. Kelly has a loyal following from Sunderland. They are not just undercard acts. They are headliners in waiting.
Undercard Depth: More Than a Prelude
Additional bouts include rising lightweight prospect Mark Chamberlain (16-0, 12 KOs) and cruiserweight contender Cheavon Clarke (10-0, 8 KOs). The card is stacked. This is not a typical Joshua undercard. It is a showcase for British boxing’s depth.
Conclusion: Stealing the Show
The main event features Joshua, a two-time heavyweight champion. But the undercard carries the real narrative. Sheeraz and Kelly have the potential to deliver fight-of-the-night performances. Agyarko could cause an upset. Zachenhuber could derail Sheeraz’s momentum.
Fans should watch the full card. The next British superstars are ready to emerge.
