Woods is out with left knee and Achilles injuries. He has not won a tournament since the Australian Masters 18 months ago. He dropped four places in the new rankings published Monday.
Lee Westwood of England remains at No. 1, with Charl Schwartzel of South Africa taking Woods' place in the top 10.
Second-ranked Luke Donald missed his chance to overtake compatriot Westwood and become No. 1 after losing in the final of the World Match Play Championship to Ian Poulter on Sunday.
The last time Woods was ranked outside the top 10 was April 1997, before he won the Masters for the first of his 14 majors.
