Former World No.1 Kim Clijsters has withdrawn from the ongoing Western & Southern Open.

"I'm grateful to Western & Southern Open for the opportunity to play the tournament once again," Clijsters said in a statement as per the WTA website. "I have great memories from playing in Cincinnati and was looking forward to being a part of the event this year. It's disappointing to have to withdraw but after discussions with medical and my team, I need a little more recovery time."
