UFC fans are waiting for some of the biggest names to make their return to the octagon, but they shouldn't expect these two marquee fighters to return any time soon. 

Brothers Nick and Nate Diaz have both been out of action for longer than either the UFC or its fans want, and the prospect of their return sounds less-than-promising. The talented brothers have been at odds with Dana White for years.

Nick hasn't fought since January of 2015, while Nate's last fight was a loss to Conor McGregor at UFC 202 in August of 2016. Rumors have swirled that Nate could be lining up a return-fight against Tony Ferguson, but Diaz confirmed huge UFC news that says otherwise. 

Diaz joined the MMA Hour on Wednesday, holding an incredibly candid interview with host Ariel Helwani. Nate made it clear that neither he or his brother are fighting in the UFC in 2017, with the brothers focused on some "serious" triathlon races.

"I'm taking a year off with my brother, you know what I'm saying? We're doing some serious races this year, we have a schedule, we have it lined up," Diaz said.

Nate took several shots at the UFC, Conor, Dana White and the managers involved with the promotion throughout the podcast which lasted over an hour. White has since responded, and he sounds pessimistic about the prospect of ever seeing the Diaz brothers fight for the UFC again.

“I don't know if those guys will ever fight again. We offer them fights all the time,” White told TMZ Sports.

“We offer fights and they turn them down. I don't know what he wants. That's up to them. If they want to fight next week, or if they never want to fight again, that's up to them. It's not up to me.

“They don't seem like they want to fight, either one of them," White said. 

Nick has been out of action since serving an 18-month suspension for testing positive to marijuana metabolites following his match against Anderson Silva at UFC 183. He's since been cleared to fight by the Nevada State Athletic Commission since December 2016.

Nate's biggest beef with taking a fight against Ferguson, or any of the other fights the UFC has sent to them, is feeling disrespected that he'd be doing the "dirty work" for superstar Conor McGregor while he waits on the potential of a huge payday with Floyd Mayweather. 

There's clearly some bad blood between Nate and the UFC, and the brothers seem to be perfectly content focusing on racing to fulfill their competitive and training needs.
