All week, Woods had mostly managed to mask the pain, walking with an almost imperceptible limp. On the course, it was clear he was in pain as he grimaced after many shots and often had to pause to compose himself before walking to his ball.
On Monday, as he walked toward the bluffs for his last round of interviews, he could barely make it up the hill, and he was no longer trying to mask a limp.
He conceded that he had risked further damage by playing the U.S. Open, and he said it was possible that he had indeed made it worse. During Monday's press conference, a reporter asked about long-term ramifications.
"As far as future ramifications, I'm not really good at listening to doctor's orders too well," he said.
A follow-up question pressed Woods, asking: "Did they tell you, though, that you could further injure it, Tiger, if you played?" He simply nodded yes. He was then asked if he had indeed injured it further. He simply answered "maybe."
He does not know when he will play next and is even uncertain if he will show up at Royal Birkdale in five weeks for the British Open. When asked about the year's third major, he said, "To be honest with you, I really don't know."
For the moment, very little is known about the knee except that it's hurting him and he isn't going to be playing in the near future.
"I think I need to shut it down for a little bit," Woods said. "It's a bit sore. I need to take a little bit of a break."
