​Ultimate Fighting Championship (UFC) is live TODAY (Sat., Sept. 12, 2026)with Noche UFC 4, streaming live online via Paramount+. The event takes place inside Desert Diamond Arena in Glendale, Arizona. Our main event tonight is Jean Silva vs. Jose Delgado in the Featherweight division.Noche UFC 4 PreviewOur main event pits Silva versus Delgado, but that’s not what UFC had initially booked for this annual event. Delgado, a native of Arizona, comes in to replace Yair Rodriguez (more on that here). Delgado comes into this one after close wins over Austin Bashi and Andre Fili. Silva, meanwhile, is coming off a close-ish win over Arnold Allen. That’s his only fight since getting finished by Diego Lopes in last year’s Noche UFC event (re-live that here).This is a huge opportunity for Delgado to catapult himself up the Featherweight rankings, while a massive risk for Silva. And a win here, over his short-notice opponent, won’t get him that much in return.The co-main event has former Flyweight champion, Brandon Moreno, taking on The Ultimate Fighter (TUF) 33 winner, Joseph Morales. That really tells you how far Moreno has fallen in the division’s title picture. As with Delgado, Morales has a huge chance to make himself a name in the division here.Rounding out the main card is Manon Fiorot vs. Alexa Grasso, Waldo Cortes-Acosta vs. Curtis Blaydes and Tommy McMillen vs. Marwan Rahiki.McMillen has been the star of fight week, as far as our traffic numbers go anyway (here’s why). The training partner of Sean O’Malley has generated significant attention for himself with his comments (like this) leading up to this one. He has also earned attention through his exciting fighting style, which has earned him two stoppage wins in UFC. Rahiki also has two stoppages and these two are projected to have a stand-up war tonight … for as long as it lasts.Noche UFC 4 Start Date and TimeNoche UFC 4 “Prelims” will begin at 2 p.m. ET.Noche UFC 4 main card is scheduled to start at5 p.m. ET.All of Noche UFC 4 airs on Paramount+, which you can stream here.The live blog here starts rolling below at 2 p.m. ET.
