Conor McGregor’s highly-strung fight week ahead of UFC 264 continued at Friday night’s ceremonial weigh-ins as he threatened Dustin Poirier’s life after facing off with his rival.

McGregor is looking to bounce back from his second-round TKO defeat to “The Diamond” at UFC 257 in January as the pair meet for a third time with the scores level at one win apiece.

But, with the bookmakers currently leaning towards his opponent, McGregor has seemingly been hell-bent on trying to get under Poirier’s skin throughout fight week.

And, after his press conference jibes involving Poirier’s wife appeared to have little effect on the Louisiana lightweight, McGregor got a little dark with his pre-fight prediction when talking to Joe Rogan following the final faceoff at the ceremonial weigh-ins.

“Joe, in 16 hours time this man is gonna learn that if you disrespect a person’s kindness and take it as a weakness, you must pay,” he said, before raising his voice and jabbing his finger in the direction of Poirier.

“Tomorrow night I’m gonna make this man pay with his life! And I mean it! 

“You’re dead in that octagon tomorrow night!”

Despite McGregor’s chilling pre-fight rhetoric, Poirier seemed unruffled and, when asked by Rogan what McGregor’s words meant to him, he said simply, “It means nothing – it’s noise.

“Tomorrow night, tune in. I want to thank you all for the cheers, the boos. I love you all.”

Poirier then paid tribute to a youngster in the crowd who had travelled to Las Vegas from his own home town.

“I want to give a shout out to a young man in the audience, a real fighter from Lafayette, Louisiana,” he said.

“Peyton Murphy, keep fighting brother. You’re the real fighter.”

Twenty-one-year-old Murphy suffers from a rare form of bone cancer, and Poirier recently helped raise $30,000 to help Murphy’s family during Peyton’s ongoing treatment.
