It wouldn’t be a major UFC event without a last-minute twist, and UFC 320, headlined by the explosive light heavyweight title rematch between Magomed Ankalaev and Alex Pereira, just gained some heavyweight insurance. Former champion Jiri Prochazka has confirmed he will serve as the official backup fighter for the main event, ensuring that this anticipated title clash will proceed even if fate throws a late curveball.
Jiri Prochazka is Locked in as the Backup
After weeks of speculation, Prochazka made it official in an appearance on “The Ariel Helwani Show” and via his own social channels: he will cut weight, make championship weight, and stand ready in Las Vegas should either Ankalaev or Pereira withdraw. The decision energizes a card already considered one of the strongest lineups of the year, providing added stability at the top and making UFC 320 must-see entertainment.

The move is telling about UFC’s current landscape: with so many title fights plagued by withdrawals in recent years, the role of a designated backup fighter has taken on real significance. For Prochazka, it’s both a gesture of professionalism and an opportunity. As he’s already fighting Khalil Rountree Jr. on the card, his presence looms large over the championship picture, one late twist and the Czech samurai could be back fighting for gold.
The Main Event: Ankalaev vs. Pereira 2
UFC 320’s headline bout features champion Magomed Ankalaev putting his newly won light heavyweight crown on the line in a rematch against one of MMA’s most decorated striking icons, Alex Pereira. The backdrop is full of intrigue: Ankalaev snapped Pereira’s short but ferocious title run at UFC 313 in March, dominating the Brazilian over five rounds. At 33, Ankalaev enters as a heavy favorite, boasting a 14-fight unbeaten streak.

Pereira, for his part, has staked his legacy on doing the improbable again. A former multi-division megastar in Glory Kickboxing, he exploded onto the UFC scene, capturing middleweight and then light heavyweight gold in breakneck time, including knockout wins over the likes of Jamahal Hill, Jiri Prochazka, and Khalil Rountree Jr.. But age is now a question; at 38, “Poatan” is aiming to prove he can flip the script on Ankalaev and reclaim championship status.
Jiri Prochazka vs. Khalil Rountree Jr. Could Steal the Show
Prochazka isn’t just waiting in the wings, he is also scheduled to face Khalil Rountree Jr. in a high-stakes light heavyweight clash on the UFC 320 main card. This matchup is significant for title implications and adds another layer to Prochazka’s hectic fight week. A former champion with one of the most all-action styles in the game, Prochazka stands as both potential crisis-solver and show-stealer.
