Britain’s Laura Robson has confirmed she will not be taking part in the US Open later in the year, as she continues to recover from having surgery on her left wrist.
The world number 79 has only played two matches in 2014, and has already missed the French Open, while also being ruled out of Wimbledon, which begins next Monday.
It has been a frustrating year for the 20-year-old, who has been treated by Dr. Richard Berger, the same surgeon who has operated on former US Open champion Juan Martin del Potro throughout his persistent wrist injury problems.
The next stage of recovery for the former junior Wimbledon champion will be to start hitting a sponge ball in August, and it remains unclear as to when she will return to competitive action, with the next Grand Slam that she would be available for being the Australian Open in January 2015.
Robson said that she is hoping to get some competitive practice towards the end of the year, and that her rehabilitation has been going well since undergoing surgery in May.
The former British number one told the BBC: "At the moment it's kind of a day-to-day thing in terms of pain and how the inflammation is going, but rehab seems to be coming along nicely.
"I'd still like to be able to play some matches at the end of this year and get some competitive tennis in before Australia.
"I'm basically going to be playing some very small tournaments to try and get my ranking up again."
The injury has troubled the former world number 27 since the off season in late 2013, and the problem persisted at the beginning of the 2014 season.
Robson has not recorded a victory on the tour this year, as she was knocked out in the opening round of the Hobart International and the Australian Open in January by Yanina Wickmayer and Kirsten Flipkens respectively.
That has forced her to miss the last five months of action, and it has stunted steady progress that had been made by the Australian-born player until that point.
She became the first British woman to reach the top 30 of the world rankings since Jo Durie in 1987 after she reached the fourth round at Wimbledon in 2013, and she also became the first British woman to reach that stage at SW19 since Sam Smith in 1998.
That followed a run to the fourth round of the US Open the previous year, where she beat Grand Slam winners Kim Clijsters and Li Na along the way.
Robson has not been able to progress from that success however, as she parted company with coach Miles Maclagan in October last year after just four months of working together, and her world ranking has dropped by 35 places in 2014.
