Merab Dvalishvili enters tonight’s main event on an historic run. The champion has defended his title an astounding three times already in 2025, most recently against Cory Sandhagen just two months ago at UFC 320. With a 14-fight winning streak and a seemingly bottomless gas tank, Dvalishvili continues to compete at an alarming frequency rarely seen at a championship level.
Success tonight would make him the first UFC champion to successfully defend his title four times in one calendar year. While other fighters rest and recover between bouts, Dvalishvili has taken a different path entirely. His relentless style and willingness to fight frequently have made him the most active champion on the roster.

Petr Yan faces a monumental challenge on the surface. The former champion was comprehensively beaten in their first meeting at UFC 314 in March 2023, where Dvalishvili controlled all 25 minutes and set a UFC record with 49 takedown attempts. Yan landed just 11 of those attempts, getting controlled for the entire duration.
However, Yan has suggested that injuries limited him significantly in that first fight. The perennial contender has used the intervening time productively, extending his winning streak to three consecutive victories including a dominant decision over Marcus McGhee last summer. Now Yan seeks redemption and a path back to reclaiming the belt he once held.

Historic Flyweight Championship Duel to Follow
Before the bantamweight title goes up for grabs, flyweight ruler Alexandre Pantoja makes his third straight December title defense at T-Mobile Arena. The Brazilian superstar will face 2025 breakout star Joshua Van in what promises to be a fascinating stylistic matchup.
Pantoja has dominated the 125-pound division with four consecutive successful title defenses and eight straight wins, sparking serious discussions about his place among all-time great flyweights. His latest outing saw him submit Kai Kara-France at UFC 317 in dominant fashion. Meanwhile, Joshua Van represents the new generation, moving from his UFC debut in June 2023 to a 5-fight winning streak and a No. 1 contender ranking at just 24 years old.
Van‘s dynamic athleticism and developing skills could prove dangerous if Pantoja isn’t razor-sharp. However, Pantoja currently operates at an elite level, leaving many wondering if this dynamic youngster is truly ready for championship gold.
Stacked Card Delivers on Multiple Fronts
Beyond the title fights, UFC 323 features several compelling matchups. Former flyweight champion Brandon Moreno faces rising prospect Tatsuro Taira in what could determine the next title contender. Henry Cejudo returns for his final fight against emerging standout Payton Talbott, a bout carrying immense weight given Cejudo’s legendary career.
Light heavyweight action opens the main card with former champion Jan Blachowicz facing surging finisher Bogdan Guskov. Blachowicz looks to halt a 3-fight winless streak, while Guskov has earned four consecutive stoppage victories and seeks to establish himself as a legitimate threat at 205 pounds.
“On paper, this is the best card of the year, surpassing last month’s outstanding lineup at Madison Square.”
