Nadal out of Mason Tourney

Cincinnati, OH (FOX19) - When the Western and Southern Open begins in Mason, Rafael Nadal won't be there.  The world's third ranked player has withdrawn because of an injury to his left knee.

The same injury forced Nadal to sit out the Olympics.  He hasn't competed since losing in the second round at Wimbledon.

Nadal will be the only player ranked in the top ten not competing in Mason.
