Ivanovic needs 1-2 weeks of rest for thigh injury

WIMBLEDON, England -- Ana Ivanovic will rest for one to two weeks to recover from a thigh injury that forced her to quit her fourth-round Wimbledon match against Venus Williams.

The French Open champion said on her website Tuesday she has a small muscle tear in her left thigh. She says the injury is very painful but not serious.

Ivanovic lost the first set against Williams on Monday, then won the opening game of the second set before stopping.

Ivanovic, once ranked No. 1, plans to play her next tournament in Los Angeles, starting Aug. 3.
