The April 9-12 Masters has been uppermost in his mind but he accepts he will have to take things on a day-by-day basis.

"As far as intention, yes, that's always been an intent," Woods said of playing at Augusta National. "As far as reality, that's two different things. I don't know.

"That's the most frustrating thing is the uncertainty. Everyone heals at different rates. I couldn't tell you and my surgeon can't tell you, trainers can't tell you.

"It is frustrating from that standpoint because I want to look forward to something, but I just look forward to day-by-day and I've had to learn how to process that.

"It's not the easiest place to come back," he said, referring to the prospect of making his first competitive appearance next year on the ultra-long and undulating Augusta layout.

"Would I want that scenario to happen? No, I wouldn't want it to. But if I can play, then I'd like to be able to tee it up."

Woods, who is two pounds lighter than when he triumphed at Torrey Pines in June, said he had started to hit full shots over the last two weeks but that his game was ring-rusty.

"As I've progressed through my shorter clubs, hitting fuller shots, you remember what it was like when you hit a full shot," he added.

"For me, the last time I really hit a full shot was at the (U.S.) Open. It didn't feel very good but it's something that everyone has to overcome and has to go through.
