World number three Roger Federer has pulled out of next month's Shanghai Masters to rest and recover after a gruelling summer, the Association of Tennis Professionals (ATP) said on Friday.
"I have some nagging injuries that I need to address and I look forward to returning to the ATP World Tour as soon as possible."
The 16-times grand slam champion suffered a five-set loss to U.S. Open champion Novak Djokovic in the semi-finals at Flushing Meadows before arriving in Australia to aid Switzerland's return to the Davis Cup World Group.
"I have very fond memories of Shanghai so I will miss this amazing tournament and all my loyal Chinese fans, but I look forward to returning to China next fall," said Federer.
