Ultimate Fighting Championship (UFC) is just over 24 hours away from its upcoming UFC Vegas 123 mixed martial arts (MMA) event, headlined by a 155-pound showdown between lightweight contenders Renato Moicano and Tom Nolan. The action gets underway this Sat. night (Oct. 31, 2026) on Paramount+ from inside the promotion’s Meta Apex facility in Las Vegas, Nevada, and also features a 170-pound co-headliner between grizzled welterweight veteran Randy Brown and unbeaten division prospect Jacobe Smith.

Before the Paramount+ live stream gets underway this weekend in “Sin City,” which includes the bantamweight showdown pitting Yana Santos against Luana Santos, as well as the flyweight fracas between Ode Osbourne and Cody Durden, all 24 fighters must hit the scale to prove themselves worthy. Note: Nevada State Athletic Commission (NSAC) affords a one-pound allowance in non-title fights.
