Injury forces Nadal to pull out of U.S. Open
August 16 , 2012
Rafael Nadal has pulled out of the U.S. Open due to a persistent knee injury.
The Spanish world number three has not played since suffering a second-round defeat by low ranked Czech Lukas Rosol at Wimbledon in June.
Nadal also missed the London Olympics due to a recurrence of tendinitis in his knees and went on to miss ATP Tour events in Toronto and Cincinnati.
The tendinitis first appeared when he withdrew from the 2008 Tennis Masters Cup. A year later, the same problem forced him to miss the opportunity to defend his title at Wimbledon.
The injury also saw him withdraw from the Australian Open in 2010 while in March this year, he pulled out of a semi-final clash with Andy Murray at the Sony Ericsson Open in Miami.
The next big event for Nadal will be the semifinal of the Davis Cup when Spain face the United States on September 14.
