The replay I saw on NBA tv clearly showed him getting a hard elbow in the face/neck area. It was definately no flop. In fact it should have been called as a flagrant foul as it looked like the guy did it on purpose, sort of as an afterthought.
But as someone here said, who needs enemies with fans like this? It's pathetic the lack of concern for your own players and one of our most consistent and best players to boot.
