Serghei Spivac, UFC Vegas 95

Watch: Serghei Spivac submits Marcin Tybura with beautiful armbar in UFC Vegas 95 main event

The Ultimate Fighting Championship returned to us tonight, August 10, 2024 for UFC Vegas 95, going down live from the UFC Apex in Las Vegas, Nevada.

Headlining the event tonight was a heavyweight rematch between no. 8 ranked Marcin Tybura (25-9) and no. 9 ranked Serghei Spivac (17-4).

Tybura won their first fight via unanimous decision back in 2020, winning all three rounds on two of the three judges’ scorecards.

Tybura was going into that fight off a defeat to Augusto Sakai (KO), while Spivac went in off a win over Tai Tuivasa (arm-triangle choke).

Since their first fight Poland’s Tybura had gone 7-2, defeating the likes of Maxim Grishin (UD), Ben Rothwell (UD), Greg Hardy (TKO), Walt Harris (TKO), who defeated the Moldovan in his UFC debut, Alexandr Romanov (MD), Blagoy Ivanov (UD), and Tai Tuivasa (rear naked choke), the defeats coming to Alexander Volkov (UD) and interim UFC heavyweight champion Tom Aspinall (TKO).

Spivac on the other hand had gone 6-2 since losing to Tybura, defeating the likes of Carlos Felipe (MD), Jared Vanderaa (TKO), Aleksei Oleinik (UD), Greg Hardy (TKO), Augusto Sakai (TKO), and Derrick Lewis (arm-triangle choke), his two defeats coming to Tom Aspinall (TKO) and former interim champion Ciryl Gane (TKO).

As you see these two have a number of common opponents; Tybura has a win over a name Spivac lost to (Walt Harris), Spivac has two wins over names Tybura lost to (Augusto Sakai, Derrick Lewis), they each beat Tai Tuivasa and Greg Hardy, and they each lost to Tom Aspinall.

Official Result: Serghei Spivac def. Marcin Tybura via submission (armbar) at 1:44 of round one

Spivac landed a good right hand once the bout began, soon after shooting in on a takedown where he partially took Tybura’s back along the fence. He fell to his side in attempt to take the back, and nearly secured the position before Tybura picked his right hook off and ended up in top position.

It didn’t take long from here and Spivac went for an armbar from his guard, beautifully shifting his hips and flipping Tybura over as he finished the fight with it less than two minutes into the opening round.


Serghei Spivac once again proves he can be a serious problem in the UFC’s heavyweight division. No one had ever submitted Marcin Tybura before in 33 professional MMA fights, and he’s a BJJ black belt.

Though he’s lost a few times: to an athletic, heavy hitter in his UFC debut at just 24 years of age, a far more experienced Tybura in his 12th pro fight, and then the two of the current top three heavyweights in the world in Tom Aspinall and Ciryl Gane.

Spivac is still only 29 years of age.

As a heavyweight, he has a wealth of time to continue improving and potentially become the best in the world some day.

The Moldovan contender improves to 17-4 as a professional tonight, 15 of those victories coming via finish (11 in the first round) with seven knockouts and now eight submissions.

I became a fan of combat sports when I was 12 years old. I was scrolling through the channels and landed upon Versus, where WEC was televised. Urijah Faber fought Jens Pulver for the second time that night. That's the first fight I ever saw, and I was immediately hooked. So eventually, I began covering the sport in the fourth quarter of 2018, and have since started writing about animals as well.
