Former world number one Tiger Woods says he has "nothing to look forward to" in his recovery from back surgery.
The 39-year-old 14-time major winner has not swung a golf club since operations in September and October.
Asked about his return, he said: "I've no answer. Neither does my surgeon or physio. There's no timetable.
"There's nothing I can look forward to, nothing I can build towards. Where's the light at the end of the tunnel? I don't know."
Woods had two operations to alleviate pain from a pinched nerve.
Revealing that he has spent most of his time playing video games, the American said he had not done any rehabilitation work on his back and that physical activities were limited.
"I walk and I walk. I'm just walking, and that's it," said Woods, whose last major victory was at the US Open in 2008.
