Daniel Omielanczuk

Daniel Omielańczuk is a Polish heavyweight born in 1982 who has been a professional mixed martial artist and kickboxer since 2009. After building a solid 15-3 record over four years in Eastern European regional circuits, particularly Konfrontacja Sztuk Walki, he signed with the UFC in spring 2013. His promotional debut was a high point: he knocked out fellow newcomer Nandor Guelmino in the third round at UFC 165 in September 2013, signaling he could finish elite opponents. Over the next four years, however, Omielańczuk went 4-3 in the UFC against increasingly ranked competition, struggling to string together wins. Key losses to Stefan Struve (submission, R2 2016), Timothy Johnson (split decision, R3 2017), and Curtis Blaydes (unanimous decision, R3 2017) saw him lose three straight, leading to his release in 2017.

As a fighter, Omielańczuk is a heavyweight with submission expertise (47% of his wins come by submission) and a secondary finishing threat in the striking game (16% KO/TKO rate). He lands the bulk of his significant strikes at range (59%), though the clinch and ground work account for 41% of his output. His takedown defense sits at 68%, but he attempts submissions regularly, giving his bouts an unpredictable grappling dimension that can keep fans engaged.

Post-UFC, Omielańczuk has been active in Absolute Championship Berkut and Konfrontacja Sztuk Walki, where he currently ranks #5 in the heavyweight division. While his higher-level competition window may have passed, he continues to compete and represents the international heavyweight journeyman: someone with craft, durability, and willingness to fight anywhere, but without the elite athleticism or consistency that carries a sustained title run.
