Woods had back surgery on September 16, 2015. In late March 2016, he announced that he would miss the Masters while he recovered from the surgery; he had also missed the 2014 Masters due to a back problem. "I'm absolutely making progress, and I'm really happy with how far I've come," he explained in a statement. "But I still have no timetable to return to competitive golf." However, he did attend the Masters Champions Dinner on April 5, 2016. For the first time in his career, he missed all four majors in one year due to problems with his back. In October 2016, he told Charlie Rose on PBS that he still wanted to break Jack Nicklaus's record of 18 major titles. Woods underwent back surgery in December 2016 and spent the next 15 months off the Tour. He made his return to competitive golf in the Hero World Challenge.
Won seven times en route to capturing the inaugural FedExCup, cruising through the PGA TOUR Playoffs for the FedExCup with two wins and a T2 in three starts. Captured 13th career major championship (second all-time to Jack Nicklaus' 18) and finished the year with 61 official PGA TOUR victories, fifth all-time. Adjusted scoring average was 67.79, matching own record set in 2000. With 60 official rounds, won his seventh career Vardon Trophy and also captured the Byron Nelson Award.
In the days and months following Woods' admission of multiple infidelities, several companies re-evaluated their relationships with him. Accenture, AT&T, Gatorade and General Motors completely ended their sponsorship deals, while Gillette suspended advertising featuring Woods. TAG Heuer dropped Woods from advertising in December 2009 and officially ended their deal when his contract expired in August 2011. Golf Digest suspended Woods's monthly column beginning with the February 2010 issue. In contrast, Nike continued to support Woods, as did Electronic Arts, which was working with Woods on the game Tiger Woods PGA Tour Online. A December 2009 study estimated the shareholder loss caused by Woods's affairs to be between $5 billion and $12 billion.
In November 2009, the National Enquirer published a story claiming that Woods had had an extramarital affair with New York City nightclub manager Rachel Uchitel, who denied the claim. Two days later, around 2:30 a.m. on November 27, Woods was driving from his Florida mansion in his Cadillac Escalade SUV when he collided with a fire hydrant, a tree, and several hedges near his home. He was treated for minor facial lacerations and received a ticket for careless driving. Following intense media speculation about the cause of the accident, Woods released a statement on his website and took sole responsibility for the accident, calling it a "private matter" and crediting his wife for helping him from the car. On November 30, Woods announced that he would not be appearing at his own charity golf tournament (the Chevron World Challenge) or any other tournaments in 2009 due to his injuries.
Surgery: Pulled out of next two PGA TOUR starts, the Genesis Open and The Honda Classic. Released statement: "My doctors have advised me not to play the next two weeks, to continue my treatment and to let my back calm down. This is not what I was hoping for or expecting. I am extremely disappointed to miss the Genesis Open, a tournament that benefits my foundation, and The Honda Classic, my hometown event. I would like to thank Genesis for their support, and I know we will have an outstanding week." In April, announced on his website he had undergone further back surgery. The operation was performed by Dr. Richard Guyer of the Center for Disc Replacement at the Texas Back Institute.
