According to MMA Junkie
A source who witnessed the scene, Diaz and Miller locked eyes while passing each other in the hallway between the dressing rooms and the pressroom as the post-event press conference took place. Words were exchanged, and Diaz allegedly threw a water bottle at Miller. The two were immediately broken up by members of their respective camps and Showtime officials.
"(Nick Diaz vs. Jason "Mayhem" Miller) would be a great fight to promote," Scott Coker said. "It's not hard to promote that fight. But we'll see if they really want to do fight in the cage. It's one thing to have them bump in to each other in the hallway and call each other names. But if they really want to fight in the cage, if anybody can put it together, we can put it together."
