Diaz only willing to fight Poirier at welterweight: ‘F-ck a weight class’

Nate Diaz has no interest in fighting Dustin Poirier at lightweight.

Nate Diaz has no interest in returning to the UFC at 155 pounds, declaring himself a welterweight in a recent post on social media.

“[Nick Diaz Army] soldier 170 pounds,” Diaz wrote on Tuesday. “Come get you some of the real.”

The former UFC lightweight title challenger and fan favorite then followed up with a Tweet aimed at Dustin Poirier, urging ‘The Diamond’ to jump up a weight class to settle their long-running feud outside the cage.

“These are fighting words tho. So f-ck a weight class,” Diaz posted in response to Poirier, who is seemingly open to a grudge match with The Ultimate Fighter 5 winner at 170 pounds.

“Does it make sense in the lightweight division? No,” Poirier told ESPN’s Marc Raimondi in a recent interview. “Does it make sense standing in the door front of a title shot? No. But it’s a fun fight and this is entertainment and this is fighting.”

Poirier is fresh off a stunning second-round KO victory over Conor McGregor at UFC 257 while Diaz is looking to rebound from his ‘BMF’ title loss to Jorge Masvidal at UFC 244 that saw Diaz busted up and finished in the third round due to doctor stoppage.

Diaz and Poirier were originally scheduled to face off in a lightweight tilt back in 2018 but the latter was forced to withdraw from the bout due to injury. Poirier — the No. 1-ranked lightweight in the world — has never fought at welterweight while Diaz is 3-3 with wins over Conor McGregor, Rory Markham, and Marcus Davis.
