Brendan Allen VS Christian Leroy Duncan

Brendan Allen submitted Christian Leroy Duncan with a rear-naked choke at 2:46 of round five in the middleweight main event of UFC Fight Night: Allen vs. Duncan in Las Vegas on October 10, 2026. Allen worked effectively on the mat throughout, taking Duncan down in round two and spending over two minutes in side control while Duncan bled from an accidental eye poke — a foul that referee Marc Goddard punished with a point deduction against Duncan. Duncan disrupted Allen's rhythm in round three by scrambling from a takedown attempt to claim the back, but Allen reversed to regain top position, and the fight remained competitive through rounds four and five. With his corner telling him he needed to win the final round to account for the lost point, Duncan tried to stay upright on his front kicks, but Allen secured a body lock about 90 seconds in, dragged him down, and locked in a rear-naked choke with both hooks in — Duncan tapped shortly after the referee checked on him. In his post-fight interview, Allen called for a title shot and named former middleweight champion Dricus Du Plessis as his preferred next opponent.

Ranked #4 Brendan Allen (27-7) and #10 Christian Leroy Duncan (15-2) collide in a middleweight main event that could reshape the top of the 185-pound division. Allen rides a three-fight winning streak including a decision over Edmen Shahbazyan, while Duncan has won five straight — most recently over Jared Cannonier — after a rocky 2-3 start to his UFC tenure that makes his current form all the more compelling.
