UFC 328 delivered a heavyweight clash that shook up the division, and we've got the updated rankings to prove it. In the main card's most pivotal bout, Alexander Volkov outdueled Waldo Cortes-Acosta in a gritty three-round war, using his reach advantage and relentless leg kicks to secure a unanimous decision. The win marked Volkov's 14th inside the Octagon and his 40th career victory, instantly boosting his title contender status for the fall.

But the shakeups didn't stop there. Tyrell Fortune, a former Bellator prospect with a wrestling pedigree, made his long-awaited UFC debut in March 2026 and didn't disappoint. He earned a hard-fought decision over seasoned veteran Marcin Tybura, cracking the top 10 and proving he belongs among the division's elite.

Rizvan Kuniev also punched his ticket into the rankings after a gritty February 2025 win over Jailton Almeida. While the fight wasn't a highlight reel, Kuniev's ability to hang with top-10 talent in his Octagon debut showed he's more than ready for the big stage.

Serghei Spivac continues to be a fixture in the heavyweight conversation. Despite losses to elite names like Tom Aspinall and Ciryl Gane, Spivac bounced back in February with a tough win over Ante Delija, halting a potential losing streak and reclaiming his spot in the top 10. His resilience against top-tier competition keeps him in the mix.

Meanwhile, Curtis Blaydes remains a top-five staple, even after a tough outing at UFC 327. With wins over legends like Junior dos Santos and Alexander Volkov himself, Blaydes' consistency over the last decade speaks volumes. The division is heating up, and these rankings reflect the relentless grind of the heavyweight elite.
