Matthew “The Martyr” Wiwczaryk is an active British BKFC middleweight from Stoke-on-Trent, England. He made his BKFC debut at BKFC 68 in Newcastle in November 2024, dropping a five-round unanimous decision to Bartłomiej Król. The bout gave him valuable experience in the longer five-round bare-knuckle format. He responded well in 2025. At BKFC 77 in Birmingham, Wiwczaryk defeated Marley “The Tank” Churcher by unanimous decision, with all three judges scoring the contest 49-46. BKFC described the contest as hard-fought, and the result moved him to 2-1 in bare-knuckle competition at that point.

Holding some bare-knuckle experience before toeing the line in the BKFC, Wiwczaryk has an attritional approach built around sustained output, toughness, and the ability to stay engaged through prolonged exchanges rather than relying solely on a quick finish. He's built for war and entertaining fights!

Wiwczaryk calls himself a devout servant of Jesus Christ, a full time martial arts instructor and he carries himself as a martial artist outside of competition with respect and integrity.
