Watch The ONE Fight Night 13 Weigh-Ins And Hydrations Tests

The preparation is done, and the athletes are ready for action at ONE Fight Night 13: Allazov vs. Grigorian on Prime Video. But to make their bouts official for the packed U.S. primetime card this Friday, August 4, they have one more obligation to fulfill. 

All 20 competitors must hit the scale at the ONE Fight Night 13 Weigh-Ins & Hydration Tests to ensure they’re on point and fit to compete at Lumpinee Boxing Stadium in Bangkok, Thailand.

Fans can tune in live by watching the video below beginning at 9 a.m. ET/6 a.m. PT this Thursday, August 3.

In the main event, Chingiz Allazov will put his ONE Featherweight Kickboxing World Title on the line in an eagerly anticipated trilogy bout with fellow pound-for-pound superstar Marat Grigorian.

There’s another clash for gold in the co-main event, as ONE Flyweight Submission Grappling World Champion Mikey Musumeci defends his crown against ONE Strawweight MMA World Champion Jarred Brooks. 

The action doesn’t stop there. ONE Featherweight Muay Thai World Champion Tawanchai PK Saenchai starts his campaign in the kickboxing ranks against Davit Kiria, and former bantamweight MMA king John Lineker meets Kim Jae Woong in a battle of fearsome knockout artists. 

With the likes of Anna “Supergirl” Jaroonsak, Marcus “Buchecha” Almeida, Elias Mahmoudi, and Tye Ruotolo also on the bill, there’s world-class talent from top to bottom.

Before the fighters step onto the scale to confirm their weight, they must pass ONE’s pioneering hydration testing protocol, which promotes the health and safety of every competitor as they look for victory on the global stage.
