Getting paid to fight in the cage with rules, regulations and a referee is all well and good, but sometimes bad blood between fighters results in some of the craziest action occurring backstage for free.

In this article we’ll look at 10 infamous backstage brawls at MMA events over the years where tempers have flared and fists have started flying.

Nate Diaz vs. Clay Guida

Clay Guida holds a 2009 split decision victory over Nate Diaz and it appears that many years later there’s still no love lost between the two lightweight stars.

Diaz happened to be returning from the bathroom at UFC 199 in 2016 when he crossed paths with Guida, who was returning to his dressing room after having just been KO’d by Brian Ortega.

“I’m going to fuck you up again,” Guida told Diaz according to Justin Buchholz, who was cornering him that night.

Guida’s older brother Jason, a former fighter who Buchholz estimated weighed around 300lbs at the time, then angrily intervened and charged at Diaz, trying to push him up against a wall as the Stockton star clinched up.

“They were trying to f*cking kill each other for a good 30 or 40 seconds,” according to Buchholz, but a large group of other people managed to intervene and pull them apart before anyone was seriously hurt.

Buchholz then handed Diaz back his shirt and then watched him casually return to his seat in the arena, where shortly afterwards he’d be shown live on TV flexing and smiling without a care in the world as it was officially announced that his blockbuster rematch with Conor McGregor would go down at UFC 202.
