Nate Diaz and Clay Guida's brother, Jason got in a scuffle backstage at UFC 199. Team Alpha Male head coach, Justin Buchholz was there as Diaz was taking on a heavyweight, and he shared more details about the incident during the Stud Radio podcast.

"It was the first time I cornered with Clay's brother, Jason Guida. Like a 285 lbs huge f*cking dude," Buchholz started. "After Clay got stopped, doctors were coming in and corners were being kept outside the cage and everything. I turn around and one of the UFC stools was just shattered in 6 pieces. Jason ripped it to shreds or slammed it, and his brother just got stopped, and was flying off the handle emotionally."

"We were walking in the back after, and Clay was walking in front," he said. "Nate was walking out of the bathroom, and Clay said something to him, but Clay was discombobulated at that time too."

"He just said something to Nate. He was all like, 'Man, I'm gonna f*ck you up again' or something like that."

Buchholz said that Nate was surprised about the whole situation and likely didn't even know that Clay was just stopped on his bout. Diaz simply smiled and was like "What, motherf*cker? Are you joking?"

"Then Jason and Nate got into it. I don't know what happened, but Jason bull rushes Nate and tries to put him up against the wall," he said. "Nate has got him in a clinch. Like 50 people from the UFC come rushing into this thing. I'm standing in the middle like, 'Nooooo!'"

"It was going down. Clay was grabbing Jason, a bunch of people grabbing Nate. They were trying to f*cking kill each other for a good 30 or 40 seconds. They get broken up, and Clay's got Jason, people got Nate. I'm looking at Nate, like 'f*ck! We weren't trying to fight. I didn't know what happened.'"

Buchholz then returns Nate's shirt and Diaz walked back to sit in the crowd. Shortly after, he was seen on camera as the UFC announced his UFC 202 rematch with Conor McGregor, flexing and smiling as if nothing happened.
