Conor McGregor told Dustin Poirier that their rivalry "is not over" after suffering a horror leg break in their trilogy fight.
The Notorious suffered the injury in the dying seconds of the first round, with the bout ended via a doctor's stoppage and Poirier declared the winner.
McGregor had vowed to "kill" Poirier prior to their main event bout, but he left the arena on a stretcher and faces a long road back from the injury.
Speaking after the bout, McGregor said: "I was boxing the bleeding head off him, kicking the bleeding leg off him, usual s**** he dived to close the distance.
"This is not over! If I have to take this outside with him it's on outside I don't give a b*******.
"There was no check [on a leg kick], there was not one of them I checked."
McGregor reiterated his claim that Poirier's wife Jolie 'slid in his DMs', adding: "Your wife is in my DMs, hey baby, hit me back up I'll chat to you later on, I'll be at the after party; The Wynn night club baby."
Poirier could now face recently crowned UFC lightweight champion Charles Oliveira later this year, who McGregor described as 'timid' during the week.
Speaking ahead of the UFC 264 bout, the Brazilian said: “Timid, no. Humble. I’m humble. I know where I came from and I know where I’m going. I guarantee you, he’s just another one that will talk, talk and talk, promoting himself the entire time, and I’ll be there training. He’ll go down on his ass in front of me."
