Mateusz “Don Diego” Kubiszyn to defend title at GROMDA 26 in Pionki

Mateusz “Don Diego” Kubiszyn, the unbeaten champion of the GROMDA bare‑knuckle boxing federation, is set to make his fifth title‑defence at GROMDA 26 – “Polskie Koloseum”. The event will be held in the historic arena in Pionki, Poland, in early September. GROMDA TV will broadcast the bout. While the challenger’s identity remains undisclosed, the federation’s president said the list of candidates has narrowed to one or two possible opponents. Kubiszyn entered 2023 with a 10‑0 record and has defended the belt three times since winning it last year.

The promoter emphasized the high expected attendance and the prestige of the venue, noting that GROMDA has entered its seventh year and is regarded among the world’s leading bare‑knuckle organisations.
