UFC 331 weigh-ins just wrapped up, and all 24 fighters competing this weekend at the Crypto.com Arena in Los Angeles, California, have successfully made weight.

In the main event, UFC flyweight titleholder Joshua Van will run it back with former champion Alexandre Pantoja, who was dethroned last year at UFC 323 after dislocating his arm and losing in just 26 seconds by TKO to Van.

“The Cannibal” and “The Fearless” both successfully made weight for their title rematch, coming in at 125 pounds.

The co-main event is a potential lightweight title eliminator bout in which top contender Arman Tsarukyan takes on knockout artist Mauricio Ruffy. Ruffy came in at 155 pounds, while “Batman” weighed in at 156 pounds, making the bout official.
