Laura Robson has pulled out of Madrid with a continuing wrist injury and could miss the French Open.

The Times reports that Robson is now considering having an injection, which would leave her sidelined for six weeks. If that does not fix the problem, she could opt for surgery.

The 20-year-old has not played since the Australian Open and is now ranked 64th after reaching No. 27 last year.

"It was last year, over the clay and the grass, where I was healthy and playing well," Robson said. "I'd love to get back to that, and that's what I'm working towards."

Judy Murray, the British Fed Cup captain and Andy's mother, said Robson should not try to return too quickly.

"Andy went through a wrist injury some years ago and psychologically it's a difficult one because everything in tennis goes through your wrist," Judy Murray told the Daily Mail.

"I'm not sure when she's going to be back. You have to be careful with wrist injuries. She has not played since the Australian Open so she will be anxious to get back playing, but you can't rush that kind of injury."
