Former British number one Laura Robson will not play again this year as she continues her recovery from injury.
The world number 547 returned to competition at Eastbourne in June after 17 months out with a wrist injury.
She has played just 10 matches, winning three, since then and last featured at an ITF event in Monterrey a month ago.
"Laura's team decided it was most effective for her to spend her time training for the rest of the year," the 21-year-old's management company said.
"The last couple of months of the season offered Robson the perfect opportunity to get some wins at a lower level and gain the match sharpness she will require to force her way back into the top 100.
