Laura Robson forced out of doubles

Britain's number one Laura Robson has been forced to withdraw from the ladies' doubles at the French Open due to injury.

The 19-year-old, who exited the singles in the opening round against Caroline Wozniacki on Monday, was due to play with American Lisa Raymond.

However, according to Sky Sports News, Watson has been forced to withdraw due to lower back pain, which has troubled her in recent weeks.

Britain's number two Heather Watson also exited the French Open on Wednesday.
