Training out of Amsterdam, Netherlands, Lion Fight Muay Thai World Lightweight Champion Sergio “Samurai” Wielzen, 30, was originally from Suriname. On May 18, 2018, the Surinamese-Dutch kickboxer will make his ONE Championship debut at “ONE: Unstoppable Dreams” at the Singapore Indoor Stadium in Kallang, Singapore where he is competing against Muay Thai legend Sam-A Gaiyanghadao, 34.

Wielzen and Gaiyanghadao will compete in a Muay Thai match in the flyweight division on the ONE Super Series card. The winner will be the first ever ONE Super Series Flyweight Muay Thai Champion.

“Sam-A Gaiyanghadao is a legend in Muay Thai, and it is such an honor for me to be competing against him,” Wielzen stated. “I have so much respect for what he has done and what he has accomplished.”

“But once that cage door closes, I am only focused on one thing and that’s winning this bout,”the Surinamese-Dutch kickboxer added. “I am prepared to do whatever is necessary to get the victory and become the first ONE Super Series world champion.”

With a professional kickboxing record of 45-18-2, Wielzen is also a former It’s Showtime 61MAX world champion who has built a reputation as being an explosive striker with stunning knockout power. Despite being physically smaller than most of his opponents, he has won many of his bouts by knockout.
