ONE Friday Fights 171 card, start times and how to watch

ONE Friday Fights 171 and The Inner Circle 31 air live from Lumpinee Stadium in Bangkok on Friday, September 18. ONE has not published bout matchups for this one yet, which is unusual this close to fight week, so this piece covers what is confirmed right now: the broadcast window and how to watch. Check back on this page once the promotion locks in names, and the full lineup will go up here.

The regular Friday slot is a weekly Muay Thai and kickboxing card that ONE runs out of its home stadium, and it airs as a single continuous broadcast rather than the tiered prelims and main card structure UFC or PFL use. Lumpinee itself is the promotion's most frequent venue on the calendar, hosting this show nearly every week of the year, so the matchups are the only thing actually in question here.

Start times

• Full card: 7:30 a.m. ET (6:30 p.m. in Bangkok, 12:30 p.m. BST), Friday, September 18
