UFC Fight Night: Allen v Duncan middleweight main event in Las Vegas

The UFC returned to its Las Vegas Apex venue on Saturday 10 October 2026 for Fight Night: Allen v Duncan, headlined by a middleweight showdown between No. 4-ranked American Brendan Allen and No. 10-ranked Englishman Christian Leroy Duncan. The 12-fight card, streamed worldwide on Paramount+, started at 5 pm Pacific/8 pm Eastern and marked the promotion's first Apex event since moving away from ESPN+ to its new US streaming home. Allen entered the night chasing a top-three middleweight ranking and a possible title shot, while Duncan, on a four-fight winning run, aimed to break into the elite 185-pound tier. The co-main event pitted Brazilian lightweight Matheus Camilo against England's Jai Herbert, with a strong undercard of ranked flyweights, bantamweights and featherweights supporting the night. For UFC it was also an important business occasion, the latest test of audience numbers on Paramount+ since the broadcast switch, and for the UK and Brazilian markets it provided a rare US primetime slot. The event sat at the heart of a packed combat sports Saturday worldwide.
