Nadal fears he may miss US Open
Rafael Nadal is a major doubt for the US Open as he continues to battle an ongoing knee injury.
The world No. 3 was forced to withdraw from the defence of his Olympic title with tendonitis in his knees and has subsequently pulled out of Masters tournaments in Toronto and Cincinnati.
Nadal has not played since he was knocked out in the second round at Wimbledon in June, and admits his tendonitis remains a serious problem ahead of the final major of the year on August 27.
"I don't know if I'll be ready in time for the US Open," Nadal told Spanish TV station La Verdad. "I can't say yes or no. It is not the same as other years, and I have found it a little different."
World No. 1 Roger Federer, who returns to action in Cincinnati this week, admits Nadal's absence is a cause for concern.
"I thought for sure we would see him in Toronto, but now he missed Toronto and Cincinnati," Federer said. "It's very surprising, because it was nothing that we heard of prior to the injury.
"He played so well on clay, and then actually seemed fine at Wimbledon. He had more [recovery] time by losing earlier at Wimbledon. I'm sad for him. I hope he'll be back for the Open."
