Woods, whose last win came 18 months ago at the Australian Masters, will drop to at least No. 11 in the next world ranking published Monday. It will be the first time he is out of the top 10 since he was No. 13 on April 6, 1997, the week before he won the Masters for the first of his 14 majors.
Forbes, meanwhile, says he's still the No. 1 celebrity in the sports world.
Woods checks in at No. 6 on Forbes' annual "Celebrity 100" list of the most powerful people or groups in the entertainment business. Lady Gaga tops the overall rankings, followed by Oprah Winfrey, Justin Bieber, U2 and Elton John.
Miami Heat star LeBron James is the second-ranked athlete behind Woods at No. 10. Kobe Bryant of the Los Angeles Lakers is No. 14.
Forbes estimated Woods' total earnings last year to be $75 million, making him the highest-paid athlete. The magazine put Bryant's earnings for the last 12 months at $53 million, followed by James at $48 million and four-time major winner Phil Mickelson at $47 million.
Woods won't be able to improve on his golf ranking anytime soon.
He started the year at No. 2 and has been steadily dropping points. Woods, who tied for fourth at the Masters last month, withdrew from The Players Championship last week because of injuries to his left knee and left Achilles. He said on his website Monday that he will try to return June 16-19 at the U.S. Open.
"I'll do whatever is necessary to play in the U.S. Open, and I'm hopeful I can be there to compete," he said.
Woods has been atop the world ranking for 623 weeks in his career, by far the longest of any golfer since the ranking began in 1986. He had been No. 1 from June 2005 until Lee Westwood of England supplanted him last November.
Since revelations of adultery emerged Thanksgiving night in 2009, Woods has seriously contended in only one tournament - he lost in a playoff at Chevron World Challenge in December after losing a four-shot lead in the final round. He has been in the top five in only four other tournaments.
