Fighter Profile: Kiamrian Abbasov

Background

Kyrgyzstani welterweight fighting under the nickname “Brazen”, and a former ONE Championship welterweight world champion. His professional record is 24-7 with 11 knockouts.

Career timeline

• Won the ONE welterweight world championship on 25 October 2019, stopping Zebaztian Kadestam, and defended the belt during his reign.
• Lost the championship to Christian Lee, who came from behind to finish him and become a two-division champion.
• Last competed on 11 May 2024, losing a unanimous decision to Sergey Martynov.
• No bout or return has been announced. As of 1 August 2026 he has been inactive for well over two years.

Fight craft

Abbasov is a physically strong, pressure-oriented welterweight who works behind heavy hands and a persistent clinch game, wearing opponents down rather than out-pointing them from range. His title reign was built on durability and volume. The pattern in his defeats is late-fight fade — including the Lee bout, where he was ahead before being finished — and he has struggled against opponents who can maintain a higher pace over five rounds.

In the modern MMA landscape

Our wider MMA analysis mentions Abbasov only as the man Lee beat for the welterweight title. Worth adding for accuracy: he has not fought since May 2024, so he is a former champion in a period of inactivity rather than an active part of ONE’s current welterweight picture.
