(Shirtless Saturdays just aren’t going to be the same around the gym without Nick.)

MMAFighting.com’s Ariel Helwani caught up with UFC on Fox 3 headliner Nate Diaz today at the press conference today in New York for the New Jersey event and the lightweight contender revealed that he thinks his brother Nick’s days in the Octagon are over.

“Triathlon season is starting so he’s just training, getting in shape for that. [He's] concentrating on being in shape, being healthy, helping me out and coaching me for my fights. Right now, I don’t think [we'll ever see him back]. He’s just big on, like I said, just being healthy and staying in shape and not worrying about [fighting] and thinking about it. I think he’s retired. He hasn’t been into this whole fighting thing for some time, you know? Since everything that goes on with the funny wins and losses — for not just him — for me and for people on our team. I think he’s just relaxed right now and he’s pretty set on his retirement. I kind of agree with him, you know? It’s hard to say, especially when it’s somebody like my brother,” Nate explained.

“I’m not going to tell him to go fight somebody. I think he’s doing the right thing, you know? Whatever. He made enough money to just chill back, sit back and relax, you know? People don’t understand, Nick never had nothing. He came from not much, so… He complained a lot about not making much money because there’s so many people making more money than him that he works 10 times harder than, so. But they definitely paid him enough money to not have to do anything. He don’t need to fight,” he told Helwani.

So there you have it, unless Nick simply isn’t one for sharing his feelings with his friends and family, which we highly doubt, we may have seen the last of the ornery Stockton native in the cage. At least there’s still a chance we might see him join the thoughtful and caring business of boxing, where I’m sure he’ll have no problems with promoters or reporters.
