The 20 world-class martial artists set to compete in U.S. primetime this Friday, April 5, have one final step to complete before they can throw down at ONE Fight Night 21: Eersel vs. Nicolas on Prime Video.

Ahead of the highly anticipated event at Lumpinee Boxing Stadium in Bangkok, Thailand, every fighter must first hit their marks at the weigh-ins and hydration tests to confirm they’re ready for action.

The card is topped by a pair of intriguing World Title contests.
