Taimu Hisai knocks out Sitthichai at Knockout 68 in Yokohama

"

Combat sports are a harsh place, especially for legends. One of the most accomplished Muay Thai fighters and kickboxers of his generation, Sitthichai is a former Glory Kickboxing lightweight champion and Lumpinee welterweight champion, among many other accomplishments in striking sports. However, the last few years have been unkind to the 34-year-old Thai fighter as he lost four of his final five fights in ONE Championship, and has gone winless since leaving the promotion last year. Perhaps the worst of those losses happened on Saturday when Sitthichai got brutally knocked out by Taimu Hisai at Knockout 68: Knockin’ on the World in Yokohama, Japan. While Sitthichai has been stopped in a couple of his recent bouts, those losses came from body shots. This time, the 20-year-old Hisai, who stepped in on short notice and moved up a weight class to take the fight, slept the legend with a brutal uppercut that not only knocked him out cold but literally took him off his feet.
