Laura Robson will miss the US Open in August as she continues to recover from the wrist injury that has derailed her 2014.
The British no. 2 has already withdrawn from Wimbledon next month but has further delayed her return from the persistent problem that has seen her compete in just one match this year.
Robson, 20, withdrew from the ASB Classic in December last year when she originally suffered the injury and was forced to pull out of the Hobart International a week later.
Having undergone surgery earlier in the year, she confirmed to BBC Sport that she will not compete in the final major of the year in New York but does plan on returning to the court before the end of the year.
"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," she said.
"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."
Robson is hoping to be fit in time for next year's Australian Open, the scene of her last competitive match where suffered defeat to Kirsten Flipkens.
