## Main event
Brendan Allen, ranked No. 4 at middleweight, faced the No. 10-ranked Christian Leroy Duncan of England in a five-round headliner. Allen entered on a three-fight winning streak, while Duncan had reeled off five straight victories.[3](https://www.mmafighting.com/ufc/514924/ufc-vegas-122-results-allen-vs-duncan) Duncan was effective on the feet in the opening round, landing from range and frustrating Allen, but the fight turned in the second: Duncan landed an eye poke for which referee Marc Goddard deducted a point, and Allen followed with a takedown and a dominant round on the ground.[1](https://www.ufc.com/news/ufc-fight-night-allen-vs-duncan-results) • [7](https://www.mmafighting.com/ufc/515230/brendan-allen-stops-christian-leroy-duncan-with-dramatic-fifth-round-choke-in-ufc-vegas-122-main-event)
The middle rounds split between the two men, with Allen grappling well in the third and Duncan sharper on the feet in the fourth. In the fifth, Allen initiated a takedown, pulled Duncan into him on the canvas, and locked in the fight-ending rear-naked choke at 2:46.[1](https://www.ufc.com/news/ufc-fight-night-allen-vs-duncan-results)
