Khamzat Chimaev defended his undefeated middleweight championship against former champion Sean Strickland at UFC 328 on Saturday, May 9, 2026 [1].

The bout represents a critical juncture for the middleweight division as Chimaev seeks to cement his legacy and Strickland attempts to reclaim the title.

The main event took place at the Prudential Center in Newark, New Jersey [2]. The venue holds approximately 19,500 seats [4]. This clash brings together two of the most dominant forces in the weight class, blending Chimaev's grappling prowess with Strickland's striking style.

Chimaev entered the contest as the reigning champion, having won the middleweight belt in August 2025 [5]. His undefeated streak has made him a primary target for the division's top contenders. Strickland, who previously held the title, entered the fight as the challenger aiming to return to the top of the mountain.

While some reports listed the event date as May 19, the fight occurred on May 9, 2026 [1]. The matchup was the centerpiece of a card designed to showcase the elite talent of the UFC's middleweight roster. The fight serves as a definitive test of whether Chimaev can maintain his dominance against a former champion with a proven track record of success in the Octagon.

The Prudential Center has become a frequent stop for major combat sports events in the U.S. due to its capacity and location [2]. This event follows a series of high-stakes matchups that have defined the current era of the middleweight division.
