Tiger Woods reacts after missing a putt on the 12th hole during the final round of The BarclaysTiger Woods is not sure he will be fit enough for the second leg of the FedEx Cup after a back problem hampered his challenge at The Barclays on Sunday.2013 Deutsche Bank Championship: Day OneAugust 30, 2013 10:00pm
The 37-year-old collapsed in pain after playing a shot from the fairway at the 13th hole in New Jersey after suffering from a back spasm.
The world No 1 regathered his composure to almost force a play-off with eventual winner Adam Scott - with Woods finishing one shot behind in a four-way tie for second.
However he admits he is now uncertain if he will be okay to play at the Deutsche Bank Championship in Boston due to the problem.
"That's all hypothetical," said Woods. "I just got off [the course] and I'm not feeling my best right now."
Woods, who attributed the issue to a soft hotel bed, had been struggling all week - with the pain flaring up on the final day at the 12th.
"It actually started the hole before, my little tee shot there started it and 13 just kind of accentuated it," he said.
"Oh yeah, big time. It's definitely spasming."
Woods finished the 13th with a bogey - and although he picked up shots at the 16th and 17th holes, he just missed out on a play-off when his 26-foot putt from off the green failed to go in.
"I had a chance," said Woods. "I hit a good putt. Thought I made it. It was a little double-breaker and I thought I poured it in.
"I was playing pretty good, and I was hanging right there and I was only one back. I figured I was in the perfect spot and unfortunately just couldn't finish off the rest of the day."
