Nadal is questionable for the U.S. Open Ticker - Monday, August 13, 2012 Rafael Nadal tells the Spanish TV station Laverdad that he is questionable for the U.S. Open, which begins on August 27. Nadal has not played a tournament since Wimbledon due to tendonitis in his knees. "I don't know if I’ll be ready in time for the U.S. Open," he said. "I can't say yes or no. [The injury] is not the same as other years, and I have found it a little different." http://www.tennis.com/articles/templates/news.aspx?articleid=19173&zoneid=25 Federer concerned for injured Nadal Ticker - Monday, August 13, 2012 Roger Federer says he’s concerned about the health of his longtime rival, Rafael Nadal, who hasn't played since Wimbledon due to a knee injury. "I was going to write him and check on him because I can't believe he's been out that long," Federer told reporters in Cincinnati. "I thought the Olympics, okay, that's fine. That's a personal choice. I thought for sure we would see him in Toronto, but now he missed Toronto and Cincinnati. 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 time by losing earlier at Wimbledon. So it came as big surprise now, these two pull outs for me. Even the Olympics, too. So I'm sad for him. I hope he'll be back for the [U.S.] Open." http://www.tennis.com/articles/templates/news.aspx?articleid=19171&zoneid=25 Nadal injury could be way worse than 09.....looks like he aint in the Open this time. Federer looking worried....great to see that from a great ambassador. Truly think he misses Nadal like SW19 09!
