The official World Golf Ranking showed Woods placed at 1,005, reflecting the former world number one's injury-hit two years that have seen him hardly play.
Woods, whose attempts to resurrect his career have been scuttled by a series of operations on his back since 2014, has made only one top-20 finish in the past two seasons.
The 41-year-old once held the world number one ranking for a record 683 weeks.
This year Woods' rehabilitation from injury was overshadowed by his arrest in May for driving under the influence.
Last month the 14-time major winner said he planned to seek professional help to treat pain medication dependency.
Woods, whose 79 career PGA Tour wins are three shy of Sam Snead's all-time record, has not won a major title since the 2008 US Open and has not won any event since the 2013 World Golf Championships Bridgestone Invitational.
