Thai striking ace “Smokin” Jo Nattawut faces a career-defining crossroads at ONE Friday Fights 137 when he battles rising Iranian contender Mohammad Siasarani in a featherweight Muay Thai clash on Friday, December 19, at Lumpinee Stadium in Bangkok, Thailand.
The 36-year-old striker candidly discussed his three-bout losing streak against top-tier competition while dismissing critics who question his place in ONE Championship. In fact, he still feels like he can make another run at the gold.
Nattawut emphasized that his back is against the wall heading into ONE Friday Fights 137, the promotion’s final event of 2025, declaring his intention to fight until the finish and revealing his ultimate dream of challenging for a ONE World Title.
Nattawut Addresses Critics Following Consecutive Losses Ahead of ONE Friday Fights 137
Speaking from his base in the United States, where he relocated from Thailand in 2013 after establishing himself domestically, Nattawut responded directly to critics questioning his competitive viability following defeats to exceptional strikers. The veteran rejected suggestions that his fire has diminished, emphasizing his unwavering commitment to training and competition despite recent setbacks.
“People say I’ve lost my fire or I don’t belong in ONE anymore. But that’s just a normal part of life for us [as fighters]. There are always people who love you and people who hate you. I don’t pay much attention to it anyway. We always give our best every time. I train hard. I fight hard,” Nattawut said.
His last victory came against American striker Luke Lessei in 2023, showcasing the lethal abilities that made him a fan favorite. However, three consecutive defeats have created urgency for the Thai to prove at ONE Friday Fights 137 he remains relevant among the featherweight Muay Thai division’s best competitors.
Striker’s Championship Dreams Drive Desperation Performance
Nattawut made clear the stakes of his upcoming battle with Siasarani at ONE Friday Fights 137, acknowledging that another loss could derail his aspirations of challenging for World Championship gold. The Thai veteran vowed to leave everything in the ring as he seeks to halt his skid and reignite his title pursuit.
“I’ve lost three fights in a row now. I cannot lose this time. My back is against the wall, so I have to go forward only. I cannot lose. I will definitely fight to the death this time. My dream is to challenge for the title,” Nattawut said.
At 36 years old with around 90 career bouts, Nattawut recognizes that time and momentum work against veterans seeking championship glory. A victory over the surging Iranian contender would breathe new life into his title aspirations while proving he can still compete with the division’s rising stars.
Thai Star Breaks Down Iranian Rival at ONE Friday Fights 137
Analyzing his opponent’s approach, Nattawut identified the specific attributes that make the 23-year-old Siasarani a dangerous matchup for any featherweight striker at ONE Friday Fights 137. The Thai veteran emphasized the Iranian’s relentless pressure and mental fortitude as primary threats requiring tactical adjustments.
“He’s aggressive, moves forward, and is a strong, relentless brawler. His strengths include good punching, toughness, endurance, and that craziness – that’s probably his biggest strength,” Nattawut explained.
The Team Mehdi Zatout representative brings seven victories across nine promotional appearances, including impressive wins over Mohammed Boutasaa, Sitthichai Sitsongpeenong, Liu Mengyang, and Kaito Ono. His current three-bout winning streak in kickboxing demonstrates the momentum and confidence he carries into this potential breakthrough opportunity.
Another victory over a respected veteran like Nattawut could earn Siasarani a six-figure contract and main roster spot with ONE Championship.
