Former Wimbledon finalist Sabine Lisicki has ruled herself out for the rest of the season to focus on her recovery from knee troubles.
Lisicki last played a competitive match at this year's US Open, and excited that tournament at the round of 16 in three sets against Simona Halep.
The world number 28 on Monday confirmed her knee injury had taken its toll for the year, saying in a message on her official Facebook page: " Like most of you know I've been struggling with a knee injury before and during the US Open.
"Ever since I got back to Germany I've been taken care of by Dr Müller Wohlfahrt and now Klaus Eder who have tried everything in order to get me ready for the Asian swing.
"But unfortunately my knee is not ready and I will not compete at tournaments this season. I have great support from my team and we are eager to get me back on the court asap. At the latest at start of next season."
Lisicki's best Grand Slam performance came at SW19 in 2013 when she reached the final, eventually losing to Marion Bartoli in straight sets.
