Four straight victories have built momentum that Kulabdam Sor Jor Piek Uthai believes will carry him back to ONE Championship’s global roster, yet the two-division Lumpinee Stadium Muay Thai World Champion understands opportunity means nothing without execution.
On Friday, December 19, the 27-year-old southpaw meets Thai countryman PTT Apichart Farm in a bantamweight Muay Thai showdown at ONE Friday Fights 137: Tawanchai vs. Liu inside Bangkok’s famed Lumpinee Stadium in Asia primetime, where a spectacular finish could unlock the life-changing contract that transforms careers from promising to proven.

Kulabdam’s 75-20 career record includes 11 promotional victories built against elite competition throughout his tenure with the world’s largest martial arts organization. His most recent triumph came against former ONE Bantamweight Muay Thai World Title challenger Felipe Lobo this past September, a unanimous decision showcasing both his power and evolution that extended his winning streak while solidifying his position as a legitimate divisional threat.
“I was very surprised in the last fight with Felipe because he didn’t throw any weapons at all. I’m not sure if this was because he was afraid of making a mistake and getting caught by my punches,” Kulabdam said. “But at least defeating him, a top contender in the bantamweight division, is further proof that I can fight anyone in this division’s rankings.”
That extraordinary power in his left hand has built a career on making opponents hesitant to engage, knowing one clean shot could end their night. Yet PTT represents a different type of challenge entirely. The 28-year-old veteran brings an impressive 112-24 career record into the bout, representing the kind of experienced, battle-tested adversary that defines the bantamweight Muay Thai landscape.
After losing his promotional debut in June, PTT bounced back with victory over Italy’s Alessio Malatesta this past September, proving his resilience and ability to adjust after setbacks.
Despite his recent success and devastating power, Kulabdam approaches the matchup with surprising humility while acknowledging the vast experience gap between himself and his opponent. His analysis reveals a fighter who has studied his rival carefully and identified specific holes to exploit, respecting the Thai veteran’s toughness while recognizing defensive vulnerabilities that could lead to spectacular finish.
“Honestly, I consider myself the underdog against PTT. Speaking purely on ring experience, he is far superior to me. The only thing I am confident I can compete with is my experience in small gloves,” he said.
“I’m not sure if he will dare to open up his guard and absorb my punches. If he does, I’m certainly ready to deliver. His strengths are his toughness and durability, and his weakness is his less-than-stellar defense system, which should give me plenty of openings to attack. But it all depends on whether I can drop him because he’s been so durable in his last two fights.”

Kulabdam has faced aggressive, forward-marching fighters throughout his career, believing his experience against that type of athlete will prove decisive against PTT. He drew parallels between his upcoming opponent and a familiar foe whose aggressive approach provided the perfect platform for implementing fierce counter-punches that have defined his striking arsenal.
“I’ve fought Muangthai PK Saenchai before, who has a very similar style to PTT. They constantly walk forward and throw strikes,” Kulabdam said. “If PTT keeps coming forward, I will keep punching. Whatever he throws, I will counter harder. We will have to see if he gets hit by my weapons and chooses to back down, or if I get tired from punching first.”
This contest represents more than extending his winning streak. The Thai star is aiming for the coveted six-figure contract that would elevate him back to ONE Championship’s global stage where he previously competed five times.
“I am determined to finish PTT. I am very confident that if I win via knockout, or at least win by a good-looking unanimous decision, it will be time for me to earn a contract,” he said. “I want to go back and prove myself on ONE’s global stage again. If I get the contract, I’m confident I will perform much better on ONE’s global stage than before.”
