“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.”

“I appreciate the fans’ concern and support,” Woods added. “This is unfortunate, but these things happen. I’ve been injured before and played again. It won’t be any different this time.”
