He said through a spokesman that it was "too early to tell" if he would be able to defend his title there.
Woods added in his statement that his back flared up when he was warming up on Sunday, and the problem was similar to the back spasms that he battled en route to a runner-up finish at The Barclays last August.
It's the seventh time in Woods' career and fourth time in the last five years that he has withdrawn from a tournament.
The most recent instance was in the final round of Doral in 2012, where he withdrew after 12 holes with an Achilles injury.
