Murray: Robson can't be rushed

Fed Cup captain Judy Murray believes Laura Robson cannot be too careful with the wrist injury which has blighted her season.

Robson has completed just one match in 2014, losing 6-3 6-0 to Kirsten Flipkens in the first round of the Australian Open having retired hurt from her opening match in the warm-up event in Hobart.

The Australia-born 20-year-old has now pulled out of upcoming tournaments in Morocco next week and Madrid on May 3, raising doubts about her participation in the French Open and Wimbledon.

"I'm not sure when she's going to be back," Murray said of the world number 64. "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.

"Andy went through a wrist injury some years ago and psychologically it's a difficult one because everything in tennis goes through your wrist."

The injury has come at a bad time for the former Wimbledon junior champion, who achieved a career-high ranking of 27th after becoming the first British woman since 1998 to reach the fourth round at the All England Club last year.

The left-hander, who won a silver medal with Andy Murray at the London Olympics in 2012, was ranked 46th at the end of 2013.
