Flemish tennis star Kim Clijsters has pulled out of the French Open, citing an ankle injury. A CT scan on Friday revealed the injury was healing, but fluid is still building up around her ankle, and she has opted to miss the second grand slam of the year and end her clay court season. The absence of Clijsters, 26, a two-time French Open runner-up, is a particular disappointment considering her impressive form since her return to action last summer after a twoand- a-half year break from tennis.
