Tiger Woods fell short on Sunday of a comeback at The Barclays, crumpling to his knees at one point from the pain of back spasms. The injury has Woods' availability for next week's Deutsche Bank Championship in question.

After a birdie on the 16th and 17th holes, Woods was one stroke away from tying for first with Adam Scott, who went on to win the tournament. Woods' 27-foot putt came up three inches short, according to his official website. Woods finished tied for second with a -10.

Despite his near comeback, Woods battled with back injuries for much of the tournament. The injury worsened through the week and appeared to peak on the No. 13 hole when Woods dropped to his knees and grimaced in pain.

"The tee shot there [at No. 12] started it," Woods said on Sunday, via his website. "Thirteen just accentuated it. I felt great until the teeshot at 12. I was perfectly fine."

He admitted to having "big time" back spasms on Sunday. Earlier in the week, Woods blamed the soft mattress in his hotel for giving him a sore back.

"My neck and back are a little bit stiff, it was stiff this morning after a soft bed and just one of those things, sleeping in hotels and I didn't want to push it, so just took it easy and chipped and putted," he said on Wednesday.

The injury now puts the Deutsche Bank Championship in question. When asked whether he'd be healthy for the Labor Day, Woods said: "That's hypothetical. I'm not feeling my best right now."

If Woods is able to play, he'll be paired with Adam Scott and Phil Mickelson in the first two rounds of the tournament, according to GolfWeek.com. The tournament runs from Aug. 30 through Sept. 3 at TPC Boston.
