Igor Dziąg is a Polish competitor listed as a black belt on his AJP Tour profile and in 2026 Kielce press after an AJP European Championship silver in Madrid.

GrapplerINFO results list earlier golds for Copacabana Kielce, including 2020 adult blue −82.3 kg and 2022 adult purple −82.3 kg at the Polish Championship. Public pages disagree on a current academy (Copacabana Kielce, AJP academy lines, and a 2026 Klincz Kielce coaching role), so this page does not set a team. Kielce press also calls him a seven-time Polish champion and mentions world silver and bronze without naming the year or federation. Confirm later results through the linked sources.
