Joshua Van defended his flyweight championship by knocking out Tatsuro Taira in the fifth round of UFC 328 on May 9, 2026 [4].

The victory solidifies Van's position at the top of the division after a period of uncertainty regarding his health and availability. By overcoming one of the division's top challengers, Van proves his durability and striking power in a high-stakes title fight.

The bout took place at the Prudential Center in Newark, New Jersey. The fight reached its conclusion at 1 minute and 32 seconds into the fifth round [3].

Van entered the contest with a professional MMA record of 17-2, including a 10-1 record within the UFC [1]. Taira brought a professional record of 18-2 and an 8-2 record in the UFC into the championship clash [2].

This matchup was originally scheduled for UFC 327, but an injury to Van forced the promotion to postpone the bout [5]. The delay shifted the title defense to the May 9 event, adding tension to the build-up of the fight.

The fifth-round finish ended the contest decisively, preventing the need for the judges' scorecards. Van's ability to secure a knockout late in a five-round fight demonstrates a significant level of cardiovascular endurance, a trait essential for maintaining the flyweight belt.

Following the win, Van remains the champion of the flyweight division. Taira, despite the loss, remains a prominent figure in the rankings due to his strong professional record [2].
