Beybulat Isaev made a statement in his first ONE Championship victory Friday in Singapore.
The Russian light heavyweight, who holds a muay thai record of 19-5, met Mihajlo Kecojevic in a kickboxing contest at ONE: Unbreakable 2.
Kecojevic, 13-1 in kickboxing, came out strong early, marching forward after Isaev connected a couple of good right hands, but ended up eating a massive right cross that folded him unconscious 82 seconds seconds into the opening stanza.
The 25-year-old Russian now holds a 1-1 record under the ONE Championship banner after a debut loss to Brazilian striker Anderson Silva in 2019.
