The incident took place during an interview at center court. Djokovic made reference to comments made by Roddick earlier in the week. Roddick had joked about Djokovic's apparent propensity for injuries and time outs during play in the tournament. Djokovic, in response to those statements remarked, "You know, Andy was saying I have 16 injuries in the last match. Obviously, I don't right?"

The crowd reacted with boos.

USA network reporter Michael Barkann tried to downplay the crowd's displeasure, but the boos intensified when Djokovic responded to the crowd by saying, "They're already against me because they think I'm faking everything, so it's all right."

Novak Djokovic later apologized for his comments. He faces Roger Federer in the semi-finals.ESPN.com: Djokovic beats Roddick on court, trashes him off it
