Sabine Lisicki to sit out rest of season with knee injury
BERLIN (AP) Sabine Lisicki says she will sit out the rest of the tennis season to heal a knee injury.
The 2013 Wimbledon runner-up last played at the U.S. Open and lost to Simona Halep in the fourth round.
Lisicki wrote on her Facebook page that she's been struggling with the injury before and during the U.S. Open. She did not specify which knee was injured.
Despite getting treatment from two doctors in Germany, Lisicki says ''unfortunately my knee is not ready and I will not compete at tournaments this season.''
Lisicki is ranked No. 28 in the world this week.
