UFC 199 was a major night for not only fights, but news regarding upcoming UFC events as well. In addition to Michael Bisping knocking out Luke Rockhold, and Dominick Cruz dominating Urijah Faber, it was announced that Brock Lesnar would be returning at UFC 200, and Diaz vs. McGregor II would go down at UFC 202.

With that being said, the night didn’t go down without any drama. According to Evan Rodner, who is a producer on Brendan Schaub & Bryan Callen’s ‘The Fighter And The Kid’ podcast, spoke to MMAMad.com about the incident:

“It looked like Nate Diaz got into an altercation with Jason Guida, Clay Guida’s older brother’ Rodner stated. ‘I have no idea what it was over, but all of a sudden there were a ton of bodies entering the tunnels in the back (of the arena). ‘After the scuffle had ended, Diaz walked back into the arena as though nothing had happened. he didn’t give one single f*ck.”

In addition, UFC welterweight Nicolas Dalby was present backstage, and posted on SnapChat about the incident.
