ONE Championship’s upcoming tentpole event is taking shape, with a pair of massive Muay Thai bouts added this week.

ONE Friday Fights 81: Superbon vs. Nattawut will go down on Asia primetime on Friday, September 27, inside the iconic Lumpinee Stadium in Bangkok, Thailand, and will now feature a meeting between certified knockout artists Suablack Tor Pran49 and “Left Meteorite” Kulabdam Sor Jor Piek Uthai at bantamweight as well as a featherweight clash of talented strikers Shadow Singha Mawynn and Mohammad Siasarani.

Suablack Tor Pran49 versus Kulabdam Sor Jor Piek Uthai

Suablack has been on a tear since he arrived in ONE last year. The Thai star collected four straight knockout wins to earn a six-figure contract to compete at the promotion’s marquee events on U.S. primetime. 

After collecting a couple more hard-earned victories, his incredible run was snapped by Kiamran Nabati at ONE Friday Fights 68 this past June. 

As a result, the Tor Pran49 man will be seeking to get back in the winners’ column against Kulabdam – who’ll be out to prove he deserves a place among the best strikers in the world. 

“Left Meteorite” was streaking after three straight knockouts in ONE. But he faltered against Nong-O Hama at ONE Friday Fights 58 in April, then suffered a devastating second-round knockout against Nabil Anane at ONE Friday Fights 69 last month. 

Expect a fully determined Kulabdam to give Suablack everything he’s got when they lock horns in September. The other blistering fight will see former Rajadamnern Stadium Muay Thai World Champion Shadow attempting to climb ONE’s featherweight Muay Thai ranks and extend his win streak to three. 

Shadow Singha Mawynn versus Mohammad Siasarani

The Singha Mawynn representative is coming off an impressive win over former World Title challenger Jimmy Vienot at ONE Friday Fights 68, and he hopes to carry that momentum and become the first man to defeat Siasarani in the world’s largest martial arts organization. 

The Iranian striker has four straight victories so far in the ONE Friday Fights series. His latest outing saw him pick up arguably the biggest win of his career against Thai superstar Sitthichai Sitsongpeenong at ONE Friday Fights 22 in September last year. 

Against Shadow, he will need to bring his A-game, especially if he wants to earn a highly coveted six-figure contract with ONE. 

ONE Friday Fights 81 will be headlined by an intense showdown between ONE Interim Featherweight Kickboxing World Champion Superbon and Thai mainstay “Smokin’” Jo Nattawut at featherweight Muay Thai.

Huge names like Takeru, Nong-O Hama, and Sam-A Gaiyanghadao will also be in action at the event, but the card is far from done yet. Expect more news to come out soon.
