Djokovic sorry for Andy blast

NOVAK DJOKOVIC has apologised for his verbal attack on Andy Roddick in the wake of his quarter-final victory at the US Open, claiming he had misunderstood the American's comments that he had "faked" injuries.

Third seed Djokovic's 6-2, 6-3, 3-6, 7-6 (7/5) win set up a last four meeting with world No.2 Roger Federer.

Roddick had jokingly commented that Djokovic had faked "16 injuries" during his victory over Tommy Robredo in the fourth round. But Djokovic used a courtside interview to attack Roddick, much to the displeasure of the New York crowd, who booed him off court. "I know they (the crowd] are already against me because they think I am faking everything," said the Serbian. "That's not nice to say that I have 16 injuries and that I'm faking it."

However, Djokovic later admitted: "Andy made a joke and it was a misunderstanding. I exaggerated and I reacted badly. I apologise if I reacted like that."
