Tiger Woods announced on his website that he had his second back surgery in as many years last Wednesday. He is optimistic he can return early in 2016.
The surgery was performed in Park City, Utah, by neurosurgeon Charles Rich, who also performed the initial operation on March 31, 2014.
"Tiger Woods underwent a microdiscectomy late on Sept. 16 at Park City Medical Center," Rich said.
"With the upcoming offseason, the decision was made to remove a small disc fragment that was pinching his nerve. The microsurgery was a complete success, and he was discharged Thursday night (US time)."
"This is certainly disappointing, but I'm a fighter," Woods said.
"I've been told I can make a full recovery, and I have no doubt that I will."
Woods, a 14-time major champion, will not be able to play in the Frys.com Open in October like he planned.
"I'd like to send my regrets to Frys and all those associated with the America's Golf Cup," Woods said.
"Those were two events I was really looking forward to playing. I was ready to start the 2015-16 PGA Tour season at Frys, and I was excited to join my good friend Matt (Kuchar) in Mexico City.
"I will be attending my foundation-hosted Hero World Challenge but won't be able to play. I appreciate everything that Hero does for the Tiger Woods Foundation, and I have a great personal relationship with Mr. (Pawan) Munjal (chairman and CEO of Hero MotoCorp). I look forward to being there to support my event."
Woods will begin intensive rehabilitation and soft tissue treatment within a week. Healing and recovery times are inconsistent based on physiological factors, but Woods is encouraged he can return early next year.
"I appreciate the fans' concern and support," he said.
"This is unfortunate, but these things happen. I've been injured before and played again. It won't be any different this time."
