UFC Vegas 124 streams on Paramount+ on November 7, with prelims starting at 5:00 PM ET and the main card at 8:00 PM ET. Waldo Cortes Acosta and Johnny Walker, the heavyweights headlining the rebuilt main event, won't walk out anywhere near 8:00, though. Five other main-card fights go first, which points to a realistic walkout window somewhere between 9:30 and 10:30 PM ET.
The full broadcast schedule
UFC Fight Night: Cortes Acosta vs. Walker runs a 13-fight card from the Meta Apex in Las Vegas, split into 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, not three — there's no separate early-prelims stream for this card. Seven preliminary bouts air in the 5:00 PM window, and six fights make up the main card, with Cortes Acosta vs. Walker capping the night as the final bout.
Why 8 PM isn't when the main event starts
The 8:00 PM time is when the first main-card fight begins, not when the headliners walk out. Five other main-card bouts go first, in this order:
- Andre Petroski vs. Mantas Kondratavičius (middleweight)
- Billy Elekana vs. Lucas Fernando (light heavyweight)
- Seok Hyeon Ko vs. Wellington Turman (welterweight)
- Davey Grant vs. Elijah Smith (bantamweight)
- Tatiana Suarez vs. Virna Jandiroba (women's strawweight co-main)
Only after those five are decided does the Cortes Acosta-Walker main event begin. None of the five is a scheduled five-round fight — there's no title bout on this card — which keeps the math more predictable than a night stacked with championship rounds.
Estimating the actual walkout time
The standard way to work this out for any card is to count the fights ahead of the main event and budget roughly 15 to 30 minutes for each one, covering both walkouts, the fight itself, and the gap afterward for corner work, scoring, or an instant-replay review. A fast finish barely moves the clock; a close fight that goes the distance eats closer to the high end of that range.
Applied here: five main-card fights ahead of the headliner, each running somewhere between 15 and 30 minutes once walkouts and breaks are included, points to Cortes Acosta and Walker's own walkout landing roughly 90 minutes to two and a half hours after the 8:00 PM start. That's 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 distance, earlier if several end by finish.
The card structure at a glance
The main card, in fight order:
- Petroski vs. Kondratavičius — middleweight
- Elekana vs. Fernando — light heavyweight
- Ko vs. Turman — welterweight
- Grant vs. Smith — bantamweight
- Suarez vs. Jandiroba — women's strawweight co-main
- Cortes Acosta vs. Walker — heavyweight main event
The seven-fight prelims card leads into all of that starting at 5:00 PM ET: Silva vs. Fernandes, Souza vs. Parsons, Delano vs. Magomedov, Nakamura vs. Schmid, Cachoeira vs. Milosevic, Raposo vs. Degli, and Petersen vs. Lorenço opening the broadcast.
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 covers the 5:00 PM prelims and the 8:00 PM main card 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 clock carries over: an 8:00 PM ET main card starts at 5:00 PM Pacific, a three-hour difference worth double-checking against the specific event listing rather than assuming it matches the last card watched.
Why the main card alone is worth the full sit-down
This main event wasn't the plan two months ago — Sean Brady's injury scrapped the original Bonfim vs. Brady headliner, and Cortes Acosta vs. Walker was built in its place on short notice. The co-main carries its own weight too: Suarez and Jandiroba are the women's strawweight division's No. 3 and No. 2 fighters, in a matchup that's fallen apart twice before finally happening this week. Both of those fights sit inside the same 9:00 to 10:30 PM window as the main event, so tuning in before the main card's final bout misses a genuine top-tier matchup, not just a buffer before the headliners.
The one thing worth doing with this
Treat 9:00 PM ET as a reasonable point to sit down, since it catches the Suarez-Jandiroba co-main before the main event itself, and treat 10:30 PM as a sensible outer edge rather than a hard deadline. Checking a live results feed around 9:45 is the simplest way to tell whether the main card is running fast or slow before deciding exactly when the heavyweight main event is likely to actually start.
