There's no word on whether Tiger will be able to play in this week's PGA Championship in Louisville, Kentucky.

Tiger Woods's bad back is up to its old tricks.

 

Just months after coming back from surgery to alleviate pain in his back, Tiger hurt it again Sunday at the WGC-Bridgestone Invitational in Ohio. 

He withdrew after the ninth hole of the final round. He was four strokes over par at the time.

Tiger says he actually suffered the injury on the second hole but tried to continue.
