The 39-year-old American was scheduled to face Bulgarian Tsvetana Pironkova in a last-64 clash on Wednesday.

Williams sustained the injury during her US Open semi-final defeat to Victoria Azarenka earlier this month.

The three-time Roland-Garros champion says the issue will require two weeks of rest followed by four to six weeks of rehabilitation.

Pironkova, who returned from a three-and-a-half-year absence at the US Open earlier this month and made a stunning run to the quarter-finals, now advances to the third round in Paris.
