Video: Tiger Falls To His Knees

Bad back sufferers across the land completely understood this back spasm reaction from Tiger Woods, who made a valiant effort to win the Barclays on a tweaked back by sleeping on a soft mattress.

From Doug Ferguson's game story on Adam Scott's win over Woods, Rose and others:

Woods had all four rounds in the 60s for the first time in a year on the PGA Tour, though it wasn't enough. He battled stiffness in his lower back all week, which he attributed to a soft bed in his hotel room - the second straight year he has had back issues from a mattress at this event.

In a brief interview with CBS Sports, he said it was "hypothetical" when asked if he would compete in the Deutsche Bank Championship, the next playoff event that starts Friday on the TPC Boston. The tournament gives its charity money to Woods' foundation. Woods already missed the AT&T National this year, which also benefits his foundation.

"I just got off and I'm not feeling my best right now," he said.
