Injury rules Kim Clijsters out of Wimbledon

Kim Clijsters has withdrawn from Wimbledon with a foot injury.

The US Open and Australian Open champion initially picked up the injury while dancing at a wedding and suffered a recurrence of the problem when playing at the Unicef Open in s'Hertogenbosch this week.

"I'm very, very disappointed to have to withdraw from Wimbledon after injuring my foot again at the tournament in s'Hertogenbosch," Clijsters said.

"At this moment I feel frustrated that it has to happen now before one of my favourite tournaments. I've always enjoyed being a part of the Wimbledon atmosphere but I have no other choice now but to rest, recover and to not play tennis for a few weeks."

Following the second-seeded Belgian's announcement, the players below her all move up a place, with Tsvetana Pironkova coming in at number 32.

With world number one Caroline Wozniacki given top billing, Vera Zvonareva is the new second seed, Li Na third, Victoria Azarenka fourth and former winner Maria Sharapova fifth.
