The image was as shocking as it was disturbing: Tiger Woods painfully sinking to his knees Sunday after his second shot on the 13th hole at The Barclays.

From there, he winced and grimaced but managed to gingerly complete play…and send a 26-foot putt just a few inches short of forcing a playoff with Adam Scott, who won the tournament.

“I had a chance,” Woods said. “I hit a good putt. It was a little double breaker and I thought I poured it.”

So much for playing for his sixth victory of the year and 80th on the tour. The bigger issue, as it has been with Woods, is injury. Although he said he “felt great until that tee shot at 12,” he admitted last week that he’d hurt his back and neck sleeping on a soft mattress and even joked when asked if he’d be getting a harder one, “What do you think?”

If he did replace the bed, it didn’t help much. He clearly was bothered by back spasms and his ability to play in the Deutsche Bank Championship is in doubt. That tournament begins Friday, so he has an extra day in which to recover.

“That’s hypothetical right now,” he said of playing this week. “I just got off [the course[ and I’m not feeling my best right now.”
