(CNN) -- Elena Dementieva, the women's world number five from Russia, has been forced to withdraw from Wimbledon because of a calf injury.
The 28-year-old suffered the injury during the French Open semifinal against Francesca Schiavone and was forced to retire from Roland Garros.
Dementieva has twice reached the semifinal at Wimbledon, losing to Venus Williams two years ago and Serena in 2009.
Meanwhile, Caroline Wozniacki was dealt a blow in her Wimbledon preparations when she lost to Aravane Rezai of France in the first round of the Eastbourne International event.
Wozniacki was the defending champion at the grass court event but she went down in three sets 6-4 1-6 6-3.
Elsewhere, Kim Clijsters crushed Yanina Wickmayer 6-1 6-1, Victoria Azarenka beat fourth seed Agnieska Radwanska 7-6 6-1 and 18-year-old Briton Heather Watson defeated world number 48 Aleksandra Wozniak 6-3 6-2.

Murray was beaten by American Mardy Fish in third round of the Aegon championships at Queens last week while Lleyton Hewitt beat Roger Federer to win the Gerry Weber Open in Halle.
