The former world number one Tiger Woods has announced that he will not play golf again this year due to a back injury.
The 39-year-old, who has won 14 majors, said he hopes to be fit enough to compete again early next year.
It is the second time he had undergone back surgery in 18 months.
This is certainly disappointing, but I'm a fighter. I've been told I can make a full recovery, and I have no doubt that I will. This is unfortunate, but these things happen. I've been injured before and played again. It won't be any different this time.
Former world number one Tiger Woods refused to confirm whether his season was over after missing the cut for the third straight major in the US PGA Championship.
Woods added a 73 to his opening 75 when the delayed second round was completed at Whistling Straits on Saturday, finishing two shots outside the cut on four over par.
"I hit it good enough to be where I needed to be, but I putted awful,'' said Woods, who was 17th in the Masters in April but is a combined 22 over par for this year's major championships.
"I finally figured something out today on the putting green, but the damage had already been done. Finally rolled the ball coming in and unfortunately it was too little, too late.''
Asked how much it hurt to make early exits from the US Open, Open Championship and US PGA, Woods said: "It's frustrating to miss any cuts because any time you miss a cut, you don't have a chance to win the event.
At the venue where he stamped his greatness on the sport with the lowest score to par in major golf history, Tiger Woods trudged off the 18th at St Andrews on Thursday with his spectacular decline well and truly validated by the Old Course.
As Jordan Spieth effortlessly assumed the mantle of golf's number one draw with a five-under par 67 and Dustin Johnson went two better with a 65, Woods cut a forlorn figure as he carded a ragged four-over par 76.
On the course where he posted a 19-under par 269 total in 2000, the only 269 on the horizon this week is his room number at the St Andrews Hotel, where he has stayed on every visit since that 2000 success, and even making the cut this week already looks unlikely.

Tiger Woods injured his right hand in his final round on Sunday at The Masters and after said a 'bone kind of popped out'.
Woods appeared to hit a hidden tree root when playing his second shot out of the pine straw on the ninth.
"A bone kind of popped out and a joint went out of place but I put it back in," Woods said.
"It hurt. It definitely hurt. I didn't know there was a tree root there. I drove my hand or drove the club straight into it. It didn't move. But my body kept moving.
"There was a little joint that popped out and I was able to somehow put it back in, which didn't feel very good, but at least it got back in and I could move my hand again."

Tiger Woods faces further questions over his future in golf after being forced to withdraw from the Farmers Insurance Open in California on Thursday.
Woods missed last year's Masters and the US Open after having surgery on a pinched nerve and only managed 11 holes in his first round at Torrey Pines before pulling out of the tournament.
The 14-time Major winner appeared to hurt his back after hitting his tee shot at the 12th - his third hole of the day - but carried on for eight more holes before calling it a day.
Woods said this was the first time he has experienced such a situation as he tries to manage his comeback.
Usually you don't have to wait like this. At home practising I keep going and keep going. This is different.
My glutes (gluteus maximus muscles) are shutting off. If they don't activate it goes into the lower back. I tried to activate my glutes best I could but they didn't stay activated.
Tiger Woods has said he will "keep fighting" after he plunged to new depths with the worst score of his professional career in Friday's second round at the TPC Scottsdale.
The 14-times major champion was out-of-sorts in every phase of his game as he struggled to an 11-over-par score of 82 at the Phoenix Open.
Woods was competing at Scottsdale in only his second event in five months after suffering back problems for most of last year after undergoing surgery.
