British Muay Thai and kickboxing legend Liam Harrison officially retires after bittersweet Denver firefight against Seksan

British Muay Thai icon Liam Harrison gave it his all in his catchweight (140 pounds) Muay Thai bout with fellow legend Seksan Or Kwanmuang at ONE 168: Denver last Friday, Sept. 6, but it was just not enough. After succumbing to a second-round TKO finish due to the three-knockdown rule at the hands of 'The Man Who Yields To No One,' Harrison quietly left his gloves in the middle of the cage at the Ball Arena.

Taking to Instagram, ONE Championship shared a graphic featuring 'Hitman' with the accompanying caption:

""Hitman," you're a legend 🙏 Thank you for an incredible Muay Thai career 🥊 @liambadco"

Since joining the world's largest martial arts promotion in December 2018, Harrison has given fans plenty of memorable moments inside the circle.

The Bad Company product's come-from-behind TKO victory over Muangthai PK Saenchai in April 2022 at ONE 156 will remain one of the most iconic one-round fights in the promotion's history.

Harrison's illustrious career comes to an end with 90 wins (44 finishes), 26 losses, and two draws.
