Esteban Ribovics has a habit of turning his fights into the kind of thing people rewatch on a Tuesday afternoon when they should be working. Three Fight of the Night bonuses in the UFC. A 2024 war with Daniel Zellhuber that just about every outlet with an awards column crowned Fight of the Year. And now, at 30 years old, he’s added something he didn’t have much of in his first few years in the Octagon: quick finishes against name opponents.
On Oct. 3 at UFC 332, he put King Green away in the first round. Seven weeks earlier at UFC 330, he stopped Edson Barboza in the second. That’s two stoppages in roughly two months for a guy whose UFC résumé, until recently, read like a stack of split decisions.
From Tel Aviv to Córdoba
The nickname is “El Gringo,” and the backstory explains it. Ribovics, full name Esteban Ribovics Marijan, was born in Tel Aviv on April 27, 1996. His entry point into fighting was Krav Maga, which a friend dragged him to at age 12. He liked it after one class, which is about as efficient a recruiting pitch as I’ve ever heard.
He finished high school, and at 17 he packed up and moved to Córdoba, Argentina, where he started stacking disciplines: boxing, muay thai and Brazilian jiu-jitsu. A year later he made his pro debut with Infernales de Tartagal in Salta.
That debut came on Dec. 12, 2015, against Lautaro Iturbe, and Ribovics won with an inverted triangle choke in the third round. Remember that one the next time somebody tells you he’s purely a striker. He then went 7-0 over his next seven fights, every one of them a finish.
The regional belts followed. On Dec. 10, 2020, he knocked out Javier Basurto in the first round to win the Fusion FC interim lightweight title. On Feb. 12, 2022, he did the same thing to Franco Aranda for the Samurai Fight House lightweight championship. Then in August 2022 he walked onto Dana White’s Contender Series and stopped Thomas Paull in 90 seconds to earn his UFC contract.
Here’s the stat I like most from that stretch. All three of his career losses have come inside the UFC, which means he arrived undefeated. Undefeated prospects off the Contender Series are a dime a dozen, but unbeaten ones who finished nearly everybody tend to be worth a second look.
The UFC years, the wars and the robbery
His UFC debut didn’t go to script, partly because the script got rewritten. Ribovics was booked against Kamuela Kirk at UFC 285 on March 4, 2023, Kirk pulled out, and Loik Radzhabov stepped in and won a unanimous decision. Four months later the Kirk fight was rebooked at UFC 290, and Ribovics took a unanimous decision of his own.
Then came a stall. He was set to face Elves Brener in November 2023 but withdrew after an accident left him unable to compete. When he came back on May 11, 2024, at UFC on ESPN 56, he flattened Terrance McKinney in the first round, which put a fair amount of rust concerns to bed in a hurry.
The fight that made him, though, was Zellhuber at UFC 306 on Sept. 14, 2024. Ribovics won a split decision in a back-and-forth brawl that collected his first Fight of the Night bonus, a President’s Choice Fight of the Year nomination at the UFC Honors awards and Fight of the Year honors from UFC.com, MMA Junkie, CBS Sports, Bleacher Report, Cageside Press, LowKick MMA and others. MMA Fighting gave it Round of the Year. MMA Mania had it No. 2. When that many outlets agree on anything, it’s usually either a great fight or a free buffet.
Next he met Nasrat Haqparast at UFC Fight Night 253 on March 1, 2025, and lost a split decision. Of the 11 media outlets that scored it, nine had Ribovics winning. That’s 82 percent of the people paid to watch closely siding with the guy who lost. Another Fight of the Night bonus took a little of the sting out, I’d guess, but only a little.
He finally got his Brener fight on Aug. 2, 2025, at UFC on ESPN 71 and won a unanimous decision. Third Fight of the Night. At that point you could set your watch by it.
The Gamrot lesson and the rebound
The real test came on April 11, 2026, at UFC 327 against Mateusz Gamrot, and Ribovics failed it. Gamrot submitted him with an arm-triangle choke in the second round. It’s the only time he’s been finished as a pro, and it happened on the mat. If you’re a matchmaker or a bettor sizing up his next opponent, that’s the data point you circle.
What he did afterward is why I’m writing this. On Aug. 15 at UFC 330 he stopped Barboza by TKO in the second round. Then on Oct. 3 at UFC 332, he stopped Green in the first.
The Green fight came with baggage. Ribovics weighed in at 156.5 pounds, half a pound over the lightweight non-title limit, so the bout went ahead at catchweight and 20 percent of his purse went to Green. His explanation, as MMA Fighting reported, was that someone in his hotel switched on the air conditioner and he “stopped sweating.” I’ve lost bets for dumber reasons, but not many.
The stoppage itself drew heat. Green told reporters he’d warned referee Herb Dean before things got bad: “I’m a little mad. I told Herb, ‘this is gonna get sticky, let me go on my shield’. I was still fine. I wanted to keep fighting.” Dana White didn’t exactly mount a defense of his referee when MMA Junkie asked. “Herb’s having a rough f*cking year. ... I’ve seen worse stoppages,” White said.
None of that changes the result in the record book. Ribovics was thrilled with it, telling UFC media afterward, “That’s what I want: a knockout.”
Where he stands and what’s next
Ribovics sits at 17-3 and No. 16 in the Knockout Daily lightweight rankings, fighting out of Kill Cliff FC. In the UFC he’s 6-3, and two of those losses were a debut against a late replacement and a split decision most of the press thought he won. Strip out the scorecards you can argue about and the only clean, undeniable loss is Gamrot.
He told UFC media after UFC 332 that he wants a top-10 lightweight in 2027. I think he’s earned the ask, with one condition. Put him across from a grappler. Barboza and Green let him do what he does best, which is stand in the pocket and make it ugly. The guys sitting in the top 10 at 155 are going to watch the Gamrot tape and try to drag him to the floor, and the way he handles that is the whole story of his ceiling.
And for the love of everything, somebody at Kill Cliff, turn off the hotel thermostat before his next weigh-in.
