Injured Federer out of Shanghai Masters

Roger Federer pulled out of next month's Shanghai Masters on Friday because of injury with the former world number one insisting he needs to rest after a grueling year.

"After consultation with my team, I have unfortunately decided to pull out of the Shanghai Masters (Oct 9-16) in order to take some necessary time to rest and recuperate after a long summer," Federer wrote on his website.

"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. 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."
