Dustin Poirier has no doubt he will face Conor McGregor again "in the octagon or on the sidewalk" following his UFC 264 victory in their trilogy fight.

Poirier was awarded the win after McGregor suffered an apparent broken leg towards the end of the first round, leaving the octagon on a stretcher with his leg in a splint.

The Irishman continued to trash talk Poirier even after the defeat. Poirier claimed McGregor repeated threats to murder him that he made in the lead-up to the fight.

Asked in his post-fight media conference if the rivalry was over, Poirier replied: "We are gonna fight again whether it's in the octagon or on the sidewalk.

"You don't say the stuff he said. He was saying that he was going to murder me, you don't say stuff like that.

"There is a chance somebody could die and you don't say that, you don't wish it on anybody."

UFC president Dana White said Poirier would fight for the lightweight title, which is held by Charles Oliveira.

However, Poirier is in no rush to start preparing for such a challenge.

"I feel like I've been preparing for a fight since last year, because I was getting ready for Conor in January, I fought him, as soon as the fight ended I knew that was next so I got home from Abu Dhabi and started training for that fight," he added. 

"I had one trip I got to decompress a little bit but I was getting ready to fight him again.

"The last thing I want to do is go home and sign a contract and start getting ready right away. I just need to get home and think about some things and spend some time with my family."
