Juan Martin del Potro has announced that he is to miss the remainder of the season while he recovers from injury.
The 26-year-old Argentine has been out of action since March due to a recurrence of the wrist problem that has dogged him in recent years.
The former US Open champion said on his official Facebook page: "Despite the positive recovery of my wrist and the progress in my overall physical condition, I have decided not to take part in the end-of-year European tournaments.
"I'm currently not at the 100% capacity required to confront this challenges. I intend to take a more patient approach to this preparation phase and focus on a sound 2015 return.
"Your constant support, good wishes and caring have been and will continue to be of the upmost importance along this journey. I am deeply thankful and I believe that during next year I'll be able to repay you, doing what I do best."
Del Potro has dropped down to 29th place in the world rankings due to his lack of action in recent months.
