Serghei Spivac vs. Vitor Petrino
UFC Fight Night · August 22, 2026 · Golden 1 Center
Petrino has the tools to win this and the takedown defense to keep it where he wants it, at least early. But Spivac is relentless about chaining attempts, and heavyweight rounds get long when a Polar Bear is leaning on you against the fence. Petrino's best path is early damage, since Spivac has been stopped by power punchers before. Slight lean to Petrino by decision or late TKO, but Spivac on top position at any point flips the fight instantly.
The Matchup
This is a genuine crossroads fight: the established top-ten grappler against the young athlete trying to take his spot. Everything hinges on the takedown battle, because Spivac lands takedowns at 59 percent but Petrino defends them at 79 percent, and one of those numbers has to give. If Spivac gets on top, his ground-and-pound and submission game can end things quickly against a fighter who has been submitted before. If Petrino keeps it standing, he is the faster, sharper, more powerful striker against a man who has been knocked out by heavy hitters. Youth and athleticism against experience and a proven ceiling.

Serghei Spivac
“Polar Bear”
Serghei 'Polar Bear' Spivac is a Moldovan heavyweight who has quietly been a top-ten fixture for years by doing the unglamorous things well. He lands takedowns at a 59 percent clip and finishes fights on the mat with smothering ground-and-pound and eight career submissions. Losses to Jailton Almeida and Waldo Cortes-Acosta knocked him back, but he rebounded with a solid decision over Ante Delija in February 2026. Still just 31, he remains one of the division's toughest outs when the fight hits the floor.

Vitor Petrino
Vitor Petrino is a 28-year-old Brazilian who rebuilt himself at heavyweight after a rough stretch at 205 pounds, and the move has paid off with three straight wins. He is a rare athlete for the division, pairing eight career knockouts with real wrestling and a 79 percent takedown defense rate. Since moving up in July 2025 he has choked out Austen Lane, flattened Thomas Petersen, and outworked Steven Asplund. Spivac is a massive step up in competition and the fight that tells us whether Petrino is a legitimate contender.
