Rafa ruled out of US Open

Rafa Nadal's ongoing knee injury has forced the world number three to pull out of the upcoming US Open.

The Spanish ace has been troubled by a knee injury that forced him to miss the Olympics this summer and has now been forced to miss the New York showpeice.
The Mallorcan also missed the recent Masters Series events in Toronto and Cincinnati because of the injury, and Nadal says he needs more time to recover.
In a statement, he said: "I am very sad to announce that I am still not ready to play and have to withdraw from this year's US Open in NYC.
"I am sorry since I always found great crowds and great support, but I have to continue with my recuperation and preparation to be ready to play in the right conditions.
"I want to say hi and thanks to all the fans, in particular to the New Yorkers. I'll miss you all this year at the Open!"
Nadal's absence will give Olympic champion Andy Murray hope he can end his long wait for a Grand Slam title although, as usual, he is likely to have to overcome Novak Djokovic and Roger Federer if he is to emerge as champion in the US.
