USA Today reported today that Woods' column in the February 2011 issue of Golf Digest - the one currently on newsstands - is his last for the publication. Statements from Golf Digest editor Jerry Tarde and from Woods himself confirmed the split. Woods has been affiliated with Golf Digest since 1997.
The decision was termed "mutual."
Just a couple weeks ago, Gillette announced it was not renewing its endorsement deal with Woods. Over the past year, Woods has lost deals with Accenture, AT&T, Gatorade, Gillette and now Golf Digest.
He still has six sponsors remaining, however ... for now. See Tiger Woods Endorsements for that list.
