ONE 172: Kaito vs. Marat Grigorian Canceled After Grigorian Fails to Provide Sample and Misses Weight, Kaito Declines Catchweight

What seemed like a smooth run at the weigh-ins for ONE 172—aside from Superlek’s slip-up that cost him his ONE Bantamweight Muay Thai title on the scales—has found a last-minute casualty. Marat Grigorian’s highly anticipated featherweight clash against Shootboxing standout Kaito has been canceled.

What was poised to be a high-level encounter between two of the division’s finest fighters fell through after catchweight negotiations failed. According to Nick Atkin, Kaito’s team declined the catchweight bout after Grigorian, who initially couldn’t provide a hydration sample during the official testing window, later succeeded but missed weight by 0.75 lbs.
