Woods, who has not played since February, fired a three-under-par 69 in the opening round of the Hero World Challenge at Albany Golf Club in the Bahamas.
The 41-year-old 14-time major champion carded five birdies and two bogeys in an encouraging first outing since injury forced his withdrawal at the Dubai Desert Classic earlier this year.
Woods underwent back surgery in April in the latest of a series of injury setbacks which also forced him to miss the entire 2015-2016 season.
The golf superstar has also battled demons in his private life, and was arrested for driving under the influence in May after being found asleep in his Mercedes-Benz by the side of the road near his home in Florida.
Woods, who was found to have five drugs including the powerful opioid hydrocodone in his system, later revealed he had undergone professional treatment to help him manage his medications.
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.
