Overview
- Joshua Van and Alexandre Pantoja both hit the 125‑pound championship limit at Friday’s official weigh-ins, so the flyweight belt remains on the line.
- All 24 fighters on the UFC 331 card recorded weights within their divisional limits, satisfying California State Athletic Commission rules that require exact weight for title bouts.
- A heated ceremonial faceoff between Arman Tsarukyan and Mauricio Ruffy nearly turned physical and required UFC CEO Dana White to step in to separate the fighters.
- Betting markets shifted during fight week to list Van as the slight favorite over Pantoja by fight night, reflecting changing public expectation for the rematch.
- The five‑round co‑main between Tsarukyan and Ruffy is being billed as a lightweight title eliminator, and the main card also features Patricio Pitbull vs. Doo Ho Choi and Gable Steveson on Paramount+.
