Tiger Woods has undergone a successful procedure to alleviate discomfort stemming from his back surgery in September.
The former world No.1 said in a statement on his website the procedure had been carried out by neurosurgeon Charles Rich in Park City, Utah, on Wednesday.
"Tiger is doing well, and we expect him to make a full recovery," Rich said in the statement.
Woods, who has previously said he expects to return in early 2016, said he had not yet set a date for his eventual comeback.
"It's one of those things that had to be done," he said. "I have an outstanding team of doctors, and I'll be back as soon as I can."
However Woods said he would be on hand to host the December 2-6 Hero World Challenge in the Bahamas which raises funds for his charitable foundation.
"I look forward to being at my event," Woods said. "Hero is a tremendous supporter of my foundation and particularly our scholars."
Woods meanwhile vowed to return to golf eventually, saying the support of wellwishers had motivated him during his recovery.
"My family and the fans' concern and support have helped a lot," Tiger said. "I'll be back, and I'll be ready to compete."
Woods struggled through a miserable 2015 campaign that included missed cuts at three straight major championships -- the US Open, British Open and PGA Championship.
He posted his worst rounds as a pro -- an 82 at the Phoenix Open and an 85 at the Memorial, even taking a break from competition early in the year to try to sort out his game and get going again in his pursuit of Jack Nicklaus's record of 18 major titles.
