WATCH: UFC's Jon Jones, Daniel Cormier brawl at promotional event

We’ve already had some grade A chatter ahead of UFC 178, light heavyweight Jon Jones’ title bout against Daniel Cormier currently scheduled for September 27. The two UFC fighters traded verbal jabs over social media after Jones posted a nasty cut above his left eye to Instagram. Cormier responded to Jones' post, claiming he would "put so many of these on your face," and that he was planning to "grind my elbow into that cut you got today." 

Those punches became very real on Monday in Las Vegas as the two brawled during a promotional event for the fight. Jones and Cormier had to be restrained by several event organizers after the whole situation deteriorated.

Strangely, UFC sent out a vine of the whole mess. I guess any publicity really is good publicity.
