Former UFC two-division champion Georges St-Pierre pushed aside talk of a potential fight with star Nate Diaz and indicated other challenges were his preference for a comeback.

UFC lightweight champ Khabib Nurmagomedov could be one of them.

St-Pierre (26-2 MMA, 20-2 UFC), who’s been dealing with health issues since coming out of retirement to capture the UFC middleweight title, told the “JRE MMA Show” that while the UFC has offered him a fight with Diaz (19-11 MMA, 14-9 UFC), the matchup offers little intrigue for either fighter.

“They said it was a done deal,” St-Pierre said. “It wasn’t a done deal. Not on my part. I don’t think it was on Nate Diaz’s part, as well. He says it’s not his fight; it’s his brother’s fight.”

Diaz recently put UFC President Dana White on blast when a matchup against St-Pierre was floated for UFC 227, which takes place Aug. 4 at Staples Center in Los Angeles. Borrowing his older brother Nick’s diss, Nate accused the promotion of selling “wolf tickets.”

The younger Diaz didn’t have much nice to say about St-Pierre, either, backing his older brother’s accusations that he was poisoned by the ex-champ via IV and that St-Pierre was allowed to fight overweight prior to a winning effort in 2013 at UFC 158.

St-Pierre dismissed the attacks as “just funny” and added, “I think (Nick Diaz) has a problem of (conspiracies).” He later mocked the scenario set forth by the onetime welterweight title challenger (via Twitter).

Aliens and Gamma rays aside, St-Pierre said he respects Nate Diaz’s abilities. He just doesn’t see much upside – and a whole lot of downside – in accepting the matchup.

“Nate Diaz is an incredible fighter, very well rounded,” St-Pierre said. “If you put yourself in my shoes there’s nothing good that can come out of it except for money, and money isn’t the only thing that drives me. If I beat Nate Diaz decisively, most people will say, ‘He took an easy fight.’”

St-Pierre ultimately sees the fight as a losing proposition, not only for his career and his legacy.

“The (critics) will say, ‘He’s a bully. He fought a smaller guy that competes at a smaller (division),’” St-Pierre said. “A lot of (lightweight) guys are bigger than me right now. He’s about the same size as me, but because I compete at 170 for most of my career, it will make me look bad. It will make me look like a bully. And this is if I win decisively.

“If I win decisively, and it’s a war back and forth, people will say, ‘Ah, he sucks.’ If I get beat? Oh my God, forget it. For my legacy it’s the end of the work I put in. It’s finished. And I could have a bad day.”

More intriguing to former welterweight kingpin and middleweight champ is the idea of taking on a threat in which he’s expected to struggle, or the possibility of adding another piece of UFC gold to his mantle.

That’s where the idea of dropping to lightweight, where he’s never fought, becomes even more enticing to face Nurmagomedov (26-0 MMA, 10-0 UFC).

“I want to do something that … at 155, I never did it before,” St-Pierre said. “The title, or beating a certain guy that’s on the rise. It could be Khabib (Nurmagomedov), (or) if there’s another guy that is unbeatable.

“If I come back like, ‘Georges is never going to beat him.’ You say never, I’m going to love it. When Dana said I would never come back, it excited me. If it’s never been done before, and it means if I do it, that will excite me. There’s a lot of things that turn me on in life. It’s women, dinosaurs and this. That really makes me go crazy.”
