Sania Mirza's continued absence from the court took a heavy toll on her singles ranking as she slid to as low as 91 in the latest WTA charts issued on Monday.
Sania, who withdrew from the US Open due to injury, dropped 21 places in one week with 380 points and runs the risk of moving out of top-100 for the first time since 2004.
Sania was forced to miss entire clay court season including the French Open and then left her singles Olympics campaign mid-way due to the niggling wrist injury.
She also lost seven positions in her doubles ranking, dropping to 44 with 949 points.
