The first round was a breathtaking affair, as Poirier landed the heaviest shots. But Olivera landed repeatedly both front kicks and knees to the torso. The effects of those kicks took hold in the second, as Oliveira tripped Poirier and ended up in top position, where he rained down heavy elbows over the course of several minutes.

Oliveira wasted little time sinking in the winning choke in the third to seal his 10th consecutive win.
