UFC Fight Night: Allen vs. Duncan streams on Paramount+ on October 10, with prelims starting at 5:00 PM ET and the main card at 8:00 PM ET. Brendan Allen and Christian Leroy Duncan headline, but five other main-card fights go first, which realistically puts their walkout somewhere in the 9:30 to 10:30 PM ET window rather than right at 8.
The full broadcast schedule
UFC Fight Night: Allen vs. Duncan runs a 12-fight card from Las Vegas in two blocks, both streaming on Paramount+.
| Segment | Start (ET) | Broadcast |
|---|---|---|
| Prelims | 5:00 PM | Paramount+ |
| Main Card | 8:00 PM | Paramount+ |
That's two blocks rather than three — this card doesn't carry a separate early-prelims stream, so all six preliminary bouts air in one 5:00 PM window before the main card begins. Six more fights make up the main card, with Allen vs. Duncan capping the night as the final bout.
Why 8 PM isn't when Allen and Duncan fight
The 8:00 PM main-card time is when the first main-card bout starts, not when the headliners walk out. Five other fights go first: a lightweight clash between Matheus Camilo and Jai Herbert as the co-main, a women's strawweight bout between Lupita Godinez and Ketlen Souza, a featherweight pairing of veterans Andre Fili and Kai Kamaka III, a light heavyweight fight pitting Julius Walker against Gerald Meerschaert moving up in weight, and a bantamweight bout between Malcolm Wellmaker and Otari Tanzilovi. Only after those five are decided does the middleweight main event begin.
None of the five fights ahead of Allen vs. Duncan is a scheduled five-round bout, since neither a title nor the main-event slot is on the line in any of them. That keeps the math simpler than a card carrying multiple championship fights, where an extra 15 to 20 minutes gets built into more than one slot.
Estimating the actual walkout time
The standard way to estimate this for any card is to count the fights ahead of the main event and budget roughly 15 to 30 minutes for each one — enough to cover both walkouts, the fight itself, and the gap between bouts for corner work, scoring, or an instant-replay review. A fast finish barely moves the clock; a close fight that goes to the scorecards eats closer to the high end of that range.
Applied here: five three-round main-card fights ahead of the headliner, each running somewhere between 15 and 30 minutes once walkouts and breaks are included, points to Allen and Duncan's own walkout landing roughly 90 minutes to two and a half hours after the 8:00 PM main-card start. That lines up with a realistic window of about 9:30 to 10:30 PM ET — later if more than one of the five earlier fights goes the full three rounds, earlier if several end by finish.

How to watch
Every fight on this card streams on Paramount+, with no separate pay-per-view purchase required — that applies to UFC Fight Nights the same way it applies to numbered events under the current broadcast arrangement. Any active Paramount+ subscription, including the entry-level plan, covers the prelims at 5:00 PM ET and the main card at 8:00 PM ET live, plus replay afterward for anyone who can't watch in real time.
Viewers outside the Eastern time zone should convert before making plans rather than assume the same clock time applies everywhere: an 8:00 PM ET main card starts at 5:00 PM Pacific, a three-hour difference worth double-checking against the specific listing for this event rather than assuming it matches the last card watched.
A fight worth catching before the main event
The co-main between Camilo and Herbert carries its own reason to tune in well before 9:30. Camilo is a 25-year-old finisher on a two-fight win streak; Herbert is a 38-year-old veteran still finishing fights with one-punch power deep into his late 30s. Both men have ended most of their career wins early rather than by decision, which is a large part of why that fight — not just the main event — carries a genuine chance of changing the night's pacing on its own. The full stakes of that matchup, and what either outcome means for both men's next booking, are covered in Camilo vs. Herbert: the 13-year gap deciding who gets to keep climbing.
The one thing worth doing with this
Treat 9:30 PM ET as the earliest realistic point to start paying close attention, and 10:30 PM as a reasonable outer edge rather than a hard deadline. Tuning in around 9:00 leaves room to catch the tail end of the fight before the main event without sitting through the full main card from 8:00 sharp, and checking a live score or results feed around 9:15 is the simplest way to tell whether the earlier fights are running fast or slow before deciding exactly when to sit down.
