With that technical and explosive battle being so close, both strikers want to fight for a more definitive result. Kongthoranee aims to prove his victory wasn’t a fluke and defend his #3 spot in the divisional rankings, while Nong-O is hungry for a slice of redemption.
In the co-main event, BJJ megastar Tye Ruotolo will defend his ONE Welterweight Submission Grappling World Title against two-time IBJJF No-Gi World Champion Dante Leon. The two sensations have been flawless in their promotional runs, but only one of them can leave Lumpinee Stadium with 26 pounds of gold and a spotless record in ONE.
