Andrew Leone, a Center Moriches native, was forced to pull out of his shot at the One FC flyweight title three days shy of the fight because of a knee injury.
Leone tweeted Wednesday that he has a slight tear of the medial collateral ligament (MCL) in his knee.
Leone (6-2) was scheduled to fight Shinichi Kojimain the Singapore-based promotion's inaugural flyweight title bout.
No replacement will be named for the One FC card on Sept. 13 in Jakarta, Indonesia. Instead, a lightweight bout between Kotetsu Boku (20-8) and Vuyisile Colossa (5-4) will be elevated to the main event.
