Robson withdraws from Sony Open
Laura Robson has pulled out of next week's Sony Open in Miami because of her ongoing wrist problems.
The 20-year-old, who added Colombian Mauricio Hadad to her coaching team last week, had been hoping to make her return in Florida.
Robson wrote on her Facebook page: "Rough day, have sadly had to withdraw from Miami due to my ongoing wrist issue."
She has not played since losing heavily to Kirsten Flipkens in the opening round of the Australian Open.
It quickly became obvious Robson was not ready and she returned home for further treatment before resuming training last month.
