People weren’t “surprised” when they heard Nate Diaz got into a “huge fight” backstage at UFC 199 this past weekend.

Apparently, Team Alpha Male’s Clay Guida and his brother Jason got into it with the bad boy from the 209 after Guida was finished by Brian Ortega.

Team Alpha Male coach Justin Buchholz was right there in the middle of all the action and told his account of what happened on Wednesday’s “Stud Radio” show.

Apparently, Guida’s head was still foggy after being knocked out by Ortega and Diaz passed by Guida and his team backstage. Guida made a comment to Diaz, which was something to the likes of f***ing him up again, as Guida beat Diaz in a split-decision fight back in 2009.

Diaz obviously took offense to the comment and the fight broke out.

Cody “No Love” Garbrandt said on the show that he talked to Diaz after the incident and was basically told the same story by Diaz.
