The octagon returns to the intimate confines of the UFC Apex this weekend, and if you are not dialed in, you are going to miss a pivotal moment in the Featherweight division. While the mainstream spotlight might be distracted by outside boxing spectacles, the real fight fans know that UFC Fight Night: Allen vs. Costa is where the savage action lives .
We are talking about a high-stakes chess match between a British boxing savant fighting for relevance and a Brazilian finisher riding the hottest streak of his life. In this complete preview, I am going to tell you exactly how to watch every punch, kick, and submission—starting with the mandatory destination at www.ufc.com—before breaking down the card, the odds, and the subtle tactical edges that will decide who gets their hand raised.
Grab your remote, log into your streaming service, and let’s get after it.
How to Tune In: The Broadcast Bible
Before we break bones, we need to break down the logistics. This is a Vegas “Fight Night” card, meaning the times are tailored for North American primetime while punishing the hardcore European crowd (as usual).
The #1 Rule: Always check www.ufc.com first. The official site is the gold standard for last-minute changes, weigh-in results, and official broadcast links specific to your country. Never trust a third-party meme account for start times; go straight to the source.
United States & Australia (Paramount+)
In a move that has become standard, the exclusive broadcast home for this event is Paramount+ .
- Prelims Start: 5:00 PM ET / 2:00 PM PT
- Main Card Start: 8:00 PM ET / 5:00 PM PT
- Main Event Walkouts (Approx): 10:30 PM ET / 7:30 PM PT
Note for Aussie fans: You are on Paramount+ as well, but you are waking up on Sunday. Set the alarm for the main card at 10:00 AM AEST .
United Kingdom & Europe (TNT Sports & HBO Max)
British fans will be burning the midnight oil to watch “Almighty” Allen try to reclaim glory.
- UK: Broadcast on TNT Sports starting at 10:00 PM BST (Prelims) with the main card at 1:00 AM BST .
- Europe: HBO Max carries the rights for the UK and Italy, while DAZN handles Germany and Austria. UFC Fight Pass is the fallback for other regions like Spain and Poland .
Rest of the World

- Africa: SuperSport (Main card at 2:00 AM CAT) .
The Main Event: A Crossroads Clash at 145 lbs
Let’s cut through the noise. The headliner features Arnold “Almighty” Allen (20-4) taking on the surging Melquizael “The Dalmation” Costa (26-7) .
This is a classic “gatekeeper vs. rising predator” scenario, but with a twist: Allen is far too skilled to be a mere gatekeeper, and Costa is far too aggressive to just be a prospect.
Arnold Allen: The Sinking Ship or the Resurgent King?
Allen is in a weird spot. Statistically, he is elite. He owns wins over Dan Hooker and Calvin Kattar. He went the distance with Max Holloway and arguably did better against Movsar Evloev than most of the division . But MMA math is cruel. He has lost three of his last four, with the most recent being a decision loss to Jean Silva at UFC 324 .
At 32, Allen is still in his prime, but his back is against the wall. The British product relies on crisp, fundamental boxing, excellent lateral movement, and a southpaw jab that breaks opponents down. However, his critics note that he has sometimes lacked the killer instinct to finish top-tier opponents in the UFC Apex .
The “X-Factor”: Allen is fighting in the Apex. He is 2-0 in this specific venue, and the smaller cage negates space. For a pressure boxer like Allen, this is a massive advantage .
Melquizael Costa: The Silent Killer
If you haven’t been paying attention to Costa, you have been asleep at the wheel. This Brazilian is legitimately terrifying right now. He is on a six-fight winning streak, and his 2025-2026 run has been a murderers’ row of violence .
He knocked out Morgan Charriere. He dismantled Dan Ige with a spinning back kick that went viral . Costa is long (5’10” with a 71″ reach), creative, and fights with a venomous confidence. He has vowed to knock Allen out, and given his recent form, that isn’t just trash talk .
The Danger: Costa is a southpaw muay Thai stylist. He uses vicious body kicks and knee strikes, and if you shoot on him, he has a black belt in BJJ with a nasty guillotine choke .
The Tale of the Tape: Southpaw Puzzle
Here is what makes this fight so fascinating for the hardcore analysts: Both men are southpaws . Usually, fighting a southpaw is awkward for orthodox fighters. Now, we have two lefties who have to recalibrate their distance.
- The Boxer vs. The Kicker: Allen wins with his hands and footwork. Costa wins with his range and versatile kicking game .
- The Pressure: Allen absorbs 3.04 significant strikes per minute. Costa absorbs 2.97. Defensively, they are similar, but Costa lands more volume (4.38 vs. 3.47) .
- The Prediction Math: Analysts are split. The betting markets have Allen as a slight favorite (-148), but sharp money is moving toward the dog, Costa (+124) .
My Take: Allen is the safer bet for a decision. He has never been finished. However, Costa is the “live dog.” If Allen’s chin has eroded slightly from the Holloway war, Costa’s length and unpredictable striking could catch him early. I lean toward Allen by gritty decision, but I won’t be shocked if Costa sleeps him in the second round.
The Undercard: “Korean Superboy” and the Future Stars
Do not change the channel after the main event. The co-main event is an absolute banger and a nostalgia trip for fans of the “Feast or Famine” era of MMA.
Doo Ho Choi vs. Daniel Santos
“The Korean Superboy” is back. Choi has been sidelined for 16 months, and at 35 years old, this feels like a last dance . He is facing Daniel Santos, a Brazilian grinder who has beaten two Korean fighters already .
- The Vibe: Choi throws heat seeking missiles. Santos throws volume and pressure. This is a “Fight of the Night” sleeper. If Choi lands the overhand right, he is the hero. If Santos drags him into deep waters, the Brazilian likely drowns him.
Malcolm Wellmaker vs. Juan Diaz
Keep your eyes on Malcolm Wellmaker. He is entering this fight as a heavy favorite (-280), and the man has dynamite in his fists. If you like heavy-handed bantamweights, this is your pit stop .
The Ground Game Alert: Modestas Bukauskas vs. Rodolfo Bellato
Don’t blink during this light heavyweight scrap. Bellato is a BJJ ace, while Bukauskas has looked reborn since returning to the UFC. This is a classic striker vs. grappler matchup on the main card .
