Kim Clijsters' injury woe has intensified after she suffered an ankle injury at a wedding, leaving her facing six weeks on the sidelines.

19920 - Kim Clijsters a serious French Open doubt

On her website the injuries were described as "a severe strain of both the medial and lateral ligaments of the right ankle and torn ligaments, a torn capsule of the ankle joint, a hematoma and torn tendon sheath", although no details were given on how she sustained the problem.

Clijsters was already set to miss a month in order to recover from shoulder and wrist injuries and, with this latest setback, she is a serious doubt for the French Open, which starts on May 17. She will also play no part in Belgium's Fed Cup semi-final against Czech Republic later this month.

Clijsters fell at the quarter-final stage at the Sony Ericsson Open in her last WTA Tour appearance, losing in straight sets to eventual winner Victoria Azarenka.
