Laura Robson out of French Open women's doubles due to back pain

British number one Laura Robson has withdrawn from the women's doubles at the French Open because of back pain.

The 19-year-old won only five games in her first-round singles defeat on Monday as she was beaten 6-3 6-2 by Denmark's Caroline Wozniacki.

Robson had been due to compete in the doubles event at Roland Garros with American Lisa Raymond, but has been advised by a doctor not to play on.

She will now return to London to prepare for the grass-court season.

Her withdrawal also comes as a blow for 39-year-oldRaymond, who has not missed a women's doubles event at a grand slam for 18 years.

Robson's next event is scheduled to be the Aegon Classic in Birmingham, which begins on 10 June, before she takes part in the Aegon International at Eastbourne five days later.

Wimbledon starts on 24 June.
