The Belgian is recovering much slower than expected after tearing a hip muscle during the Sony Ericsson Open in Florida last month. She will resume training in about three weeks.

Clijsters said Tuesday that ''my current physical condition does not allow me to be ready for Roland Garros.''

In her farewell season, Clijsters has focused on the Olympics. She will open her grass-court season at the Rosmalen tournament in the Netherlands starting June 17, one week before Wimbledon.

Tennis at the London Olympics starts July 28.
