Dustin Poirier may not have too many years left in the sport after losing to Charles Oliveira at UFC 269. There has been a lot of talk about him potentially retiring after he became champion.

The UFC lightweight contender could be done fighting and could potentially stop fighting at lightweight. There have been talks of him not fighting at all.

“The Khabib fight I felt like I was bested. I did everything I could and I lost.” Poirier said on The MMA Hour. [In the Oliveira fight], I felt I could’ve done more. That hurts. That’s something I have to deal with. I could have been smarter. I could have been more in the moment. Could have been more locked in. I could have been a world champion.”

The opportunity to become a champion in the UFC is one everybody takes very seriously. It was a crushing blow for Dustin Poirier.

“I may never get the opportunity again, to call myself world champion.” Poirier said. “To underperform… I owed it to myself, this one was for me, it wasn’t for the money. It wasn’t for proving anything. It was for me and I fucking fumbled, man. It hurts.”

It may be that Dustin Poirier won't return to lightweight. He may not even fight in the UFC again.

“I don’t know if I’m going to. I don’t know if I want to make that cut again. I might never fight at 155lbs again. I don’t know what’s going to happen. I don’t know the future.

“I could have came in at 152lbs on this fight. My cut went so smooth. I felt great. Of course that’s because I did all the things I was supposed to do in training camp. It made the cut so great, but I don’t know if I want to go through that kind of training camp again, where I’m hungry every day; competing in the gym and pushing myself on low calories. We’ll see. I don’t know. I don’t know what’s going to happen.”

UFC fans will be hoping Dustin Poirier returns and continues to fight. It will be interesting to see what the future holds.
