The Ultimate Fighting Championship's final pay-per-view event of the year is set after the UFC 310 weigh-ins.
Headlining the mixed martial arts promotion's return to Las Vegas is a flyweight championship fight between Alexandre Pantoja and Octagon newcomer Kai Asakura. Both men successfully made the weight, which wasn't a given as Asakura had previously been fighting at bantamweight. Two fighters missed weight, though, as Anthony Smith came in 1.5 pounds over the light heavyweight limit for his fight against Dominick Reyes, while Bryan Battle came in 4 pounds heavy for his welterweight contest versus Randy Brown.
