Important Lesson #1: If you tweet insults at Nick and Nate Diaz, they will brawl with you.

Hopefully, UFC rising star Khabib Nurmagomedov took that lesson to heart last night, because apparently his online heat directed at the Diaz brothers resulted in a brawl at WSOF 22. Here’s some video of what went down outside the Las Vegas venue after fists – and chairs – were thrown within (h/t to BloodyElbow):

Supposedly, WSOF brass has banned the Diaz brothers from attending future events, but they keep booking fights for known cheater Rousimar Palharaes, so it’s hard to gauge how serious they are.

Either way, mess with the Diaz brothers, get messed with. That’s a fact.
