Krzysztof Glowacki, former WBO champ and one-time KSW fighter, suspended 4 years for steroid use

Krzysztof Glowacki, whose KSW 83 knockout from his back was one of the most memorable of 2023, has been banned from all sports for four years.

Poland’s Krzysztof Glowacki, a former WBO champion, has been suspended from all sports for four years after he was found guilty of using an anabolic steroid, U.K. Anti-Doping (UKAD) said Tuesday.

According to Reuters, Glowacki, 37, failed a UKAD-administered drug test following his fourth-round TKO loss to Richard Riakporhe on Jan. 21, 2023 in Manchester, England. His urine sample contained Boldenone, an anabolic androgenic steroid on the World Anti-Doping Agency’s (WADA) list of prohibited substances.

Glowacki (32-4, 20 KOs) denied knowingly taking a prohibited substance when he received a provisional suspension last April. His case was heard by an independent National-Anti-Doping Panel (NADP) on Oct. 31, and a final decision was reached this week.

While the loss to Riakporhe was his last boxing match, Glowacki’s doping case didn’t stop him from competing in mixed martial arts with Polish promotion KSW. Last June, Glowacki made his professional MMA debut at “KSW 83: Colosseum 2” and landed one of the most memorable finishes of 2023 when he knocked out Patryk Tołkaczewski from his back while mounted.

Glowacki won his first WBO cruiserweight title in a thrilling fight with Marco Huck in 2015 then successfully defended it once before losing the belt to current heavyweight champion Oleksandr Usyk in 2016, the first defeat of his career after starting 26-0.
