Shortly after Daniel Cormier defeated Anthony Johnson to claim the UFC light heavyweight title, Ryan Bader started taunting him on twitter and calling him out. Things carried over on the UFC 187 post-fight press conference where the two fighters got heated and had to be separated by the UFC staff.

Bader was Cormier's original opponent before he stepped in to face Johnson, and kept talking about how DC didn't want to fight him.
