Dustin Poirier and Nate Diaz were set to face each other at UFC 230 in November 2018. The fight was unfortunately canceled as 'The Diamond' had to pull out due to an injury.Poirier later claimed in a Twitter post that the negotiations for the Diaz fight were not going in the right direction. Resultantly, the Louisiana native chose to address a lingering injury instead of fighting the Stockton native."He [Nate Diaz] wanted it, he just couldn't come to terms with ufc. They offered us the main event at MSG but he would only agree if it was on his terms. I was tired of playing games with the guy and that's when i decided to address a injury I had been dealing with. Now you all know #facts." Dustin Poirier wrote.He wanted it he just couldn't come to terms with ufc. They offered us the main event at msg but he would only agree if it was on his terms.

He also admitted that he might have jumped the gun regarding allegations against Nate Diaz. Poirier wrote:"And thats the whole truth with me and Nate situation ....also I jumped the gun when news came out that he failed a test. He's always been a guy who pushed for clean eating and clean sport. I shouldn't have. Doesn't change the fact that I still want to beat his a**."And thats the whole truth with me and Nate situation ....also I jumped the gun when news came out that he failed a test.
