India's Mirza pulls out of U.S. Open

NEW DELHI -- Sania Mirza has pulled out of the U.S. Open due to an ongoing wrist injury that flared at the Olympic Games.

The Indian 21-year-old said Thursday that she would be unable to take part in the final grand-slam event of the year, beginning Monday.

Mirza, who underwent surgery on her right wrist in April, was forced to retire from her first-round singles match in Beijing and had been advised to rest for three weeks. A statement released Thursday said she had undergone "intensive tests" before being advised to rest.

"It's very disappointing for me to miss the U.S. Open, I've always done well in this tournament," Mirza said.

Mirza reached the fourth round of the U.S. Open in 2005 as an 18-year-old.
