What happened: Marie Ruumet lost to Yu by decision in their 2023 Muay Thai meeting. Friday's event begins at 9 p.m. ET with broadcasts planned in more than 195 countries.
Why it matters: Yu now moves into atomweight kickboxing against former K-1 champion Kana. The rule-set change gives the earlier Muay Thai result limited value as a direct comparison.
By the numbers: Yu began her ONE tenure with six consecutive wins before losing twice in a row.
What to watch: Yu and Kana are scheduled to meet Friday at ONE Fight Night 46. Prime Video carries the U.S. and Canadian broadcast.
