Things nearly turned physical during Arman Tsarukyan and Mauricio Ruffy’s final faceoff on Friday evening ahead of their co-main event clash tomorrow night (Sat., Sept. 19, 2026) at UFC 331 LIVE on Paramount+ from inside Crypto.com Arena in Los Angeles, California. Tonight’s UFC 331 ceremonial weigh ins (see HERE) offered a ton of exciting matchups and faceoffs. This included UFC 331’s main event rematch between reigning UFC flyweight champion Joshua Van and former titleholder Alexandre Pantoja. Not to mention on-stage appearances from the likes of Gable Steveson, Patricio Pitbull, Robelis Despaigne, and Marlon Vera. UFC 331’s co-main event will be a lightweight clash between ranked contenders Arman Tsarukyan and Mauricio Ruffy. There hasn’t been a ton of bad blood between the two fighters leading up to this weekend, but on Friday tension boiled over on stage. After Tsarukyan stepped on the scale he walked over to Ruffy and tried to maneuver around his outstretched fist. Ruffy didn’t like that and the two nearly got into a pre-fight scuffle, but UFC CEO Dana White was right in the middle of it to break things up. Check out the official staredown videos below!
