Surgery: Announced on Wednesday, June 18, two days after winning the U.S. Open, that he would have reconstructive surgery on the anterior cruciate ligament in his left knee and miss the remainder of the 2008 season. Also announced that pain in his leg during the U.S. Open resulted from a double stress fracture to his left tibia, which he suffered while rehabilitating the knee. Surgery was performed on Tuesday, June 24 in Park City, Utah, by Dr. Thomas D. Rosenberg and Dr. Vernon J. Cooley, who did arthroscopic surgery on the same knee in April.


Farmers Insurance Open: In his first official PGA TOUR start in over a year, carded rounds of 72-71-70-72 to finish T23 at the Farmers Insurance Open, his 17th start in the event. Marked his first time playing the weekend at Torrey Pines since 2014, with a WD and missed cut in 2015 and 2017, respectively. Stats for the week included: 17 of 56 fairways, 42 of 72 greens in regulation and 110 putts.
Farmers Insurance Open: At the beginning of the year, committed to the Farmers Insurance Open, The Honda Classic and the Omega Dubai Desert Classic on the European Tour. Making his first start in an official PGA TOUR event for the first time since the 2015 Wyndham Championship (T10), opened the Farmers Insurance Open with a 4-over 76 on the South course, his highest score ever to start a year as a professional. Missed the 36-hole cut after a second-round 72 for a 4-over total.
Chevron World Challenge: Lost in a playoff to Graeme McDowell at the Chevron World Challenge. It was the first time as a professional that he lost after holding a three-shot-or-more lead entering the final round. McDowell drained a 20 foot putt on the 72nd hole to force a playoff and then made a 25 foot putt on the first playoff hole (No. 18) to capture the win. The world's No. 2-ranked player missed a 14-foot putt that would have extended the playoff. He has finished in the top two at this event in eight of his 10 starts.
On February 19, 2010, Woods gave a televised statement in which he said he had undertaken a 45-day therapy program that began at the end of December. He again apologized for his actions. "I thought I could get away with whatever I wanted to," he said. "I felt that I had worked hard my entire life and deserved to enjoy all the temptations around me. I felt I was entitled. Thanks to money and fame, I didn't have to go far to find them. I was wrong. I was foolish." He said he did not know yet when he would be returning to golf.[83][222] On March 16, he announced that he would play in the 2010 Masters.[223]
In November 2006, Woods announced his intention to begin designing golf courses around the world through a new company, Tiger Woods Design.[196] A month later, he announced that the company's first course would be in Dubai as part of a 25.3-million-square-foot development, The Tiger Woods Dubai.[197] The Al Ruwaya Golf Course was initially expected to finish construction in 2009.[197] As of February 2010, only seven holes had been completed; in April 2011, The New York Times reported that the project had been shelved permanently.[198][199] In 2013, the partnership between Tiger Woods Design and Dubai Holding was dissolved.[200]
THE PLAYERS Championship: In his next start, claimed on Mother's Day his second PLAYERS Championship victory after opening with a pair of 5-under 67s. He had previously not had back-to-back rounds in the 60s at THE PLAYERS since the second and third rounds in 2004 (T16). The only other time he accomplished the feat was in 2001 (second, third and fourth rounds), when he won. With his win, joined Jack Nicklaus, Steve Elkington, Hal Sutton, Fred Couples and Davis Love III as multiple winners of the event. The victory at TPC Sawgrass became his fourth of the campaign, the earliest he has achieved the feat in a season. The win was also his 16th in Florida, the most of any state. Converted the 54-hole lead for the 53rd time (in 57 attempts).
Woods collaborated closely with TAG Heuer to develop the world's first professional golf watch, which was released in April 2005.[139] The lightweight, titanium-construction watch, designed to be worn while playing the game, incorporates numerous innovative design features to accommodate golf play. It is capable of absorbing up to 5,000 Gs of shock, far in excess of the forces generated by a normal golf swing.[139] In 2006, the TAG Heuer Professional Golf Watch won the prestigious iF product design award in the Leisure/Lifestyle category.[140]
