UFC fighters involved in wild, chair-throwing brawl inside and outside arena

While Ronda Rousey's main event of UFC 190 stole the headlines, over at the World Series of Fighting 22 in Las Vegas, UFC's brothers Nick Diaz and Nate Diaz hit a new low along with Khabib Nurmagomedov.

The trio was evidently at the event supporting friends, before an all-out brawl broke free in the stands, then outside The Axis, where a fight card was being held.

After the brawl, World Series of Fighting vice president Ali Abdel-Aziz talked with MMAFighting.com, and wasn't happy.

"I can't have Nick and Nate come to a World Series of Fighting event again," Abdel-Aziz said. "I like these guys, but if they're not going to show me respect coming to the show, how can I let them back in?

"You've just got to be more professional in MMA. Nate and Nick, all the times I talk to them, they're good guys, but they need to start making a (positive) impression. I know they sell better because they don't care, but you're going to make people not like you if you do stuff like that. I know they don't care, it's attention, fights, guys want to fight each other. But you know what, fight each other in the cage. It was disappointing, to be honest with you."

Nate Diaz was handcuffed and taken away, but wasn't arrested.
