When the fight ended, Poirier mocked McGregor's strut and spewed trash talk McGregor's way and said McGregor had suffered the injury earlier in the fight when a kick was checked.
Already upset about the gruesome injury, McGregor said the issue with Poirier wasn't over and made disparaging remarks about Poirier's wife, Jolie. Hearing those remarks infuriated Poirier, who said one way or another, he and McGregor will meet for a fourth time.
"We are going to fight again whether it's in the octagon or on the sidewalk," Poirier said at his UFC 264 post-fight press conference.
As Poirier thought about the verbal sparring between the two, he thought things McGregor said during the buildup went too far.
“There’s no holds barred with the trash talk, right?” Poirier said. “But murder isn’t something you clown around with. There’s no coming back from that and this guy was saying he was going to murder me and all kinds of stuff.
"He was telling me he was going to kill me tomorrow (and that I) was going to leave here in a coffin. You don’t talk like that to people, man. I hope this guy gets home safely to his beautiful family, you know?”
