Tiger Woods: Fallen golf great has 'nothing to look forward to'

The 14-time major champion has sunk to world No. 400 after a litany of injuries and poor form saw him tumble down the rankings.

And the 39-year-old was in a particularly bleak mood Tuesday as he revealed his physical condition is so bad after another back operation that he can't even bend down to pick up a ball.

Woods underwent his third microdiscectomy surgery last month -- a procedure to remove bone around a pinched nerve to allow space for it to heal -- and admitted he has no idea when he will be back on the course.

"I have no answer for that. Neither does my surgeon or my physio," Woods said in a press conference at Albany Golf Club in the Bahamas, where this week he will host the Hero World Challenge tournament that raises funds for his charity.
