UFC 331’s Oliveira-Tsarukyan Rematch Twist Has Fight Fans Rethinking Their Card Predictions

Something strange happened on the way to UFC 331.

A fight that looked locked in. A rematch fans had circled for months. Then the promotion quietly changed the terms, and nobody outside the matchmaking room fully explained why. Charles Oliveira and Arman Tsarukyan are running it back on Saturday, September 19, but the fight that’s actually been booked isn’t the one most people expected when the rematch talk first started.

That gap between expectation and reality is the whole story here. And it’s worth digging into, because it says a lot about how fast a fight card can flip once a promotion moves one piece.

The Rematch Nobody Predicted Would Look Like This

Oliveira and Tsarukyan first met at UFC 300 in April 2024, a fight most people remember for a split decision that could’ve gone either way. Tsarukyan got the nod. Fans wanted the rematch immediately. It took a while to materialize, but Sports Illustrated reported the rebooking finally happened, with the pair headlining UFC 331 in Los Angeles.

Here’s the twist. Multiple outlets, including Bloody Elbow, reported Tsarukyan won’t be allowed to challenge for Oliveira’s BMF title in this fight. That’s odd on its face. Oliveira holds a title. Tsarukyan is fighting him in the literal main event. But the belt stays off the table. On top of that, the bout has reportedly been trimmed from a five-round scheduled fight to a shorter structure in some reports, or kept at five in others depending on the outlet, which itself tells you how much confusion is swirling around this booking.

Fans noticed immediately. It’s not every day a promotion books its two best lightweights in a rematch and then strips the obvious stakes out of it.

Seasoned fight fans don’t just shrug this off. A booking wrinkle like this changes how people read the rest of the card, and it changes how they shop for numbers before fight night. Once one fight on a card gets weird, bettors start rechecking everything else, comparing lines across multiple books because a shift in one matchup often ripples into how the whole event gets priced. That’s part of why platforms like Ohio sports betting sites have become a regular stop for fans trying to see how oddsmakers are actually pricing a card once the fine print changes. Gambling involves risk. Please play responsibly and only wager what you can afford to lose, and if it stops being fun, that’s the moment to step back.

Why strip the belt from a fight this big? A few theories are floating around. Some think the UFC wants to keep Oliveira’s BMF status flexible for a future superfight. Others think it’s simpler: matchmakers didn’t want title implications complicating a fight they’d already had trouble scheduling once. Either way, the fans left holding the bag are the ones who assumed this would be a clean, title-on-the-line rematch.

Why One Booking Change Reshapes an Entire Card’s Narrative

Think about how fans build predictions for a UFC card. It’s rarely fight-by-fight in isolation. People read the whole lineup as a story. A title fight at the top signals stakes. A non-title main event, even a great one, signals something different: this is about pride, ranking position, maybe a No. 1 contender case. Strip a title away mid-negotiation and you change the entire emotional register of the card.

Last Word on Sports framed the broader card context around this shift, and the reaction wasn’t uniform. Some fans think a non-title fight actually makes for a more honest gauge of who’s better, since neither guy has to fight cautiously to protect gold. Others feel cheated, arguing a BMF strap on the line would’ve made the stakes unmistakable.

That division matters. Bloody Elbow’s coverage of the fan reaction put it bluntly: a BMF fight between two grapplers was always going to be a hard sell to the highlight-reel crowd anyway. Take the belt away and some fans lose interest entirely. Others say it never mattered to them in the first place.

Not every twist. Some fans loved it.

What Seasoned Fans Actually Do When a Card Gets Weird

Here’s the thing about fight fans who’ve been watching this sport for a decade or more. They don’t take a promotional announcement at face value. They cross-reference it. They check three or four outlets. They wait for the actual bout agreement paperwork instead of trusting the first tweet.

That instinct is earned. Cards get reshuffled constantly. Fighters pull out. Weight classes shift. Title eliminators get quietly downgraded to non-title fights, which is exactly what appears to be happening here. A fan who predicted a clean five-round title fight in April is now looking at something structurally different in September, and that changes who they think wins, how confident they are in that pick, and how much stock they put in the “twist” narrative altogether.

UFC 331 isn’t happening in a vacuum either. The promotion has been busy. Fighters like Michael “Venom” Page are reportedly booked for a middleweight clash in Paris this September, according to reporting from SI.com, which means fans are juggling multiple cards worth of shifting stakes at once. Keeping track of what’s actually locked in versus what’s still a rumor has become its own skill.

The Broader Pattern: Promotions Love Ambiguity Right Up Until Fight Week

It’s worth zooming out here. The UFC has a long history of announcing fights before all the details are locked, then adjusting terms as fight week approaches. Round counts change. Title implications get added or removed. Sometimes it’s genuine late-stage negotiation. Sometimes it’s a promotional tactic, generating exactly the kind of “wait, what happened to the belt?” conversation this Oliveira-Tsarukyan booking has produced.

Either way, the lesson for fans paying close attention is simple. Don’t lock in your read on a card the moment it’s announced. Wait for the fine print. The gap between “rumored fight” and “official bout agreement” is where all the interesting wrinkles live, and UFC 331 is turning into a pretty good case study in exactly that.

FAQ: UFC 331 Oliveira-Tsarukyan Rematch

When is the Oliveira vs. Tsarukyan rematch happening? The rematch is set for UFC 331 on Saturday, September 19, 2026, reportedly in Los Angeles. It follows their original UFC 300 meeting in April 2024, which Tsarukyan won by split decision.

Is Oliveira’s BMF title on the line in the rematch? Reports indicate no. Multiple outlets, including Bloody Elbow, say Tsarukyan won’t be permitted to challenge for the BMF belt in this bout, despite Oliveira holding the title heading into the fight.

Why did the UFC remove the title stakes from this fight? The UFC hasn’t given an official explanation. Speculation ranges from keeping the BMF title flexible for future matchups to simplifying negotiations after a rematch that already took over a year to finalize.

How did fans react to the twist? Reaction has split. Some fans feel the fight is diminished without title stakes. Others argue a non-title bout removes incentive for cautious fighting and could produce a more telling result between two elite grapplers.

Has the round count for the fight changed too? Reporting has been inconsistent on this point, with some outlets describing a shortened format and others sticking with the standard five-round main event structure. Confirmation is expected closer to fight week.

Whatever the final format ends up being, UFC 331 has already done something rare. It’s got fans re-litigating a fight before it’s even fully booked. That’s usually a sign the promotion has a live one on its hands, twist and all.
