ONE Championship: Mohammad Siasarani finally gets coveted contract – now he wants the belt
After knocking out Jo Nattawut to secure his deal, Iranian says belief and self-discipline have carried him to brink of featherweight gold

Mohammad Siasarani was speaking with the calm certainty of a fighter who feels aligned with his moment. Days after knocking out “Smokin’” Jo Nattawut to secure a US$100,000 ONE Championship contract, the 23-year-old Iranian sounded less relieved than resolved.
“For a long time, my goal was just the contract,” Siasarani told the Post. “Now it is finished. My goal now is the belt.”
The finish itself at ONE Friday Fights 137 in Bangkok on December 19 was emphatic: a clean second-round stoppage that ended a bout many expected to become a drawn-out contest. For Siasarani, however, the result felt inevitable.
“I was seeing that knockout before the fight,” he said. “Ten days before, every day, I was writing it down. I was talking to myself and believing it would happen.”
