Injury blow for Clijsters

Kim Clijsters suffered a worrying injury setback as the second seed abandoned her opening match at the Rogers Cup in Toronto last night.

Less than three weeks before she is due to begin the defence of her US Open title in New York, and after two months out with a foot injury which caused her to miss Wimbledon, the 28-year-old Belgian pulled out of her clash with China's Jie Zheng soon after winning the opening set.
