Conor McGregor Tweets & Deletes Scathing Threats To Dustin Poirier Conor McGregor isn’t letting up on his personal insults towards Dustin Poirier. It’s rare that a trilogy fight doesn’t settle things but that’s exactly what happened with Poirier vs. McGregor 3. The fight ended at the conclusion of the first round when McGregor broke his tibia. Slow-motion footage shows that McGregor’s shin hit the elbow of Poirier, possibly causing the injury. After the fight, McGregor got nasty on the mic, slamming Poirier and his wife, Jolie. What wasn’t captured during the UFC 264 broadcast was McGregor making gun signs and threatening to kill Dustin and Jolie in their sleep.
