On the question of whether this UFC 178 media day brawl involving Jon Jones and Daniel Cormier is real or staged, let's just be safe and say it looks like something on the staged side of real.
Jones and Cormier walk up at around 0:41. The staredown turns into Jones rubbing his forehead against Cormier's, which leads Cormier to shove him away. Then, shit pops off. Or rather: "Shit" "pops off."
After the incident, Jones and Cormier took shots at each other through Twitter:
The two fight on Sept. 27, on the real side of real.
