 Safin has already qualified for the end-of-season Masters Cup |
Australian Open champion Marat Safin has pulled out of this month's St Petersburg Open and is a doubt for the Paris Masters. The Russian, world number four, has yet to fully recover from a ligament tear in his left knee.
"The knee is not yet ready," Safin said on his official website.
Safin will fly to Paris on Monday to resume training, hoping to be fit in time to defend the title he won in Bercy last year.
His last match was a 6-2 6-3 defeat to Robby Ginepri at the Cincinnati Masters on 20 August.
The St Petersburg Open begins on 24 October and the Paris Masters the following week.
