Viddal Riley puts his unbeaten record and British Cruiserweight title on the line against EBU European champion Mateusz Masternak on Saturday, April 4th at the O2 Arena in London, England. The fight is part of the undercard for Deontay Wilder vs Derek Chisora and will be broadcast live on DAZN as a pay-per-view event.
Viddal Riley is an undefeated British cruiserweight with a professional record of 13-0 (7 KOs). The 28-year-old is the reigning British Cruiserweight champion, having claimed the title on April 26, 2025 with a unanimous decision win over Cheavon Clarke on the undercard of Anthony Joshua vs Daniel Dubois at Tottenham Hotspur Stadium. Riley has been active and is looking to step up in class against a seasoned European titleholder.
Mateusz Masternak is a Polish professional boxer with a professional record of 50-6 (33 KOs). The 38-year-old is the current EBU Cruiserweight champion, a title he won for the second time by stopping Joel Tambwe Djeko in the 7th round in October 2025. A two-time European champion with over 56 professional fights, Masternak brings a level of experience Riley has not yet faced.
Riley enters as the significant favorite, but Masternak is a compelling live dog here. The experience gap between 13 fights and 56 is real, and Masternak looked sharp stopping Djeko in his most recent outing. Riley is younger and more active, but he has yet to face anyone close to Masternak’s caliber. At +237, Masternak offers genuine value for bettors who believe a seasoned European champion can exploit the gaps in a still-developing 13-fight pro.
On this page I’ve outlined the odds for the Viddal Riley vs Mateusz Masternak fight and provided a simple three step guide you can follow to bet on the fight online.
