Dustin Poirier may be fighting for the interim UFC lightweight title tonight against Max Holloway, but he may not stay in that division forever.

Since moving up to lightweight from featherweight following his loss to Conor McGregor in 2014, Poirier has compiled a stellar 8-1 record with one no contest fighting up in weight.

At lightweight, Poirier has compiled wins against top names such as Eddie Alvarez, Justin Gaethje and Anthony Pettis.

While the featherweight weight limit is now totally off the cards, Poirier thinks he may move up a weight class again some day.

“I could never make 145 again, and I never will,” Poirier said ahead of his fight at UFC 236. [H/T MMAJunkie]

“If anything, I’ll go up. Definitely a possibility. My body is just getting heavier, more dense.

“Things change as you get older, and ’55 is not fun to make anymore. Not that fighting has to be fun 100 percent of the time, but I just want to be healthy.”

And it’s his former opponent Pettis’ exploits at welterweight, where he recently handed Stephen “Wonderboy” Thompson his first ever knockout loss at welterweight, which gives Poirier confidence he could make a good run at 170 lbs.

“Those guys are so long,” Poirier continued. “It’s not so much the size – well, [Tyron] Woodley’s size is big – but I stopped Pettis, and he just stopped Stephen Thompson.

“MMA math doesn’t make sense, but [I could do it].”
