The former British No 1 started off her 2014 season at the Hobart International but had to withdraw in the first round due to a wrist injury.
Robson last played a match at the Australian Open last January, where she lost in straight sets in the opening round against Kirsten Flipkens from Belgium.
Robson subsequently had to miss out on the French Open, Wimbledon and US Open as a result of undergoing surgery on her left wrist.
The 21-year-old’s name no longer appears on the entry list for next week’s WTA Tour even in Indian Wells. She has, however, been given a wild card into qualifying in Miami in a fortnight’s time.
The Olympic mixed doubles silver medallist had hoped to be fit for this year’s first Grand Slam in Melbourne but did not make it and plans to return at low-key events in the US were shelved.
Wrist injuries are notoriously troublesome for tennis players and Robson’s team’s focus has always been on ensuring the??Briton is not rushed back before she is ready.
Assuming her progress remains on track, Robson, who no longer has a ranking, will play her first match in more than 14 months in Florida.
