What happened: The atomweight kickboxing bout is set for Aug. 14 at Bangkok's Lumpinee Stadium. The card begins at 9 p.m. ET, airing on Prime Video in the U.S. and Canada and Sky Sports in the U.K. and Ireland.
Why it matters: Yu enters after collecting seven promotional victories in Muay Thai, while Kana brings former K-1 champion credentials. The ruleset change gives both fighters a new test under the ONE banner.
By the numbers: Kana owns a 24-7 career striking record with 11 finishes. Yu's seven ONE victories have all come in Muay Thai.
What to watch: Friday will provide the first measure of how each fighter adapts to ONE's kickboxing format.
