After a stomach injury cut short the last-leg of her season, Sania Mirza slipped two rungs to 32nd in the latest WTA rankings issued on Monday.
The Indian ace, who will now be seen in action at the Hopman Cup slated from December 30, has 921 points in the latest singles charts.
In the doubles rankings, Sania hung on to her 19th spot with 1680 points. The 20-year-old's injury-layoff may leave her unseeded at the Australian Open in Melbourne next year as she would miss out on WTA ranking tournaments in the coming weeks.
Meanwhile, Belgian Justine Henin, who claimed her ninth WTA title in Zurich last week, continued her reign at the top with 5930 points.
Russian Svetlana Kuznetsova was a distant second with 3750 points and Serb Jelena Jankovic occupied the third spot with 347 points.
Jankovic's compatriot Ana Ivanovic was fourth followed by Russian Maria Sharapova at the fifth position.
In the ATP doubles rankings, Leander Paes and Mahesh Bhupathi clung to the 17th and 21st spot respectively.
