So what we heard is that Nic Diaz and Joe Riggs were in the same hospital room after their UFC fight. As Nick was getting stiched up on one side of the room, Joe Riggs was on the other side and according to Nick Joe wouldn't stop talking. So Nick says to something to the effect to Joe, "shut your mouth or I'm going to come over there and hit you." Joe kept talking, so Nick Diaz walked over and hit him! Security and personel ran in pretty quickly to break things up after that.
Wonder what the nurses thought?
Gotta say, we love Nick Diaz around here.
