The Belgian has not played since tearing a hip muscle at the Sony Ericsson Open in Florida in March, with her recovery going slower than expected.

She is scheduled to resume training in around three weeks and will then focus on winning gold at this year's Games, something she has always targeted since confirming this would be her final season on the WTA Tour.

"My current physical condition does not allow me to get into top shape for Roland Garros," she said on her official website.

"However I can not wait to begin a long period of preparation for the grasscourt season, with the main objectives Wimbledon and the Olympics."

The three-time US Open champion is due to make her comeback at the Unicef Open in Rosmalen starting on June 17, one week before Wimbledon gets underway.
