Tiger Woods is growing frustrated that he still does not know when he will be able to competitively play golf again following his car crash.

The 15-time major champion was involved in a single-car accident a year ago that left him with open fractures to the tibia and fibula in his right leg.

Woods has not played competitively since and warned in December his return was a "long way off".

But the American superstar seemingly would have hoped to be able to provide a further update by now, as he revealed his irritation when speaking at the Genesis Invitational on Wednesday.

"I wish I could tell you when I'm playing again," he said. "I want to know, but I don't."

It all begins tomorrow. This is golf elevated

Woods revealed he still has difficulty walking, although he is "getting better" – just not as quickly as he would like.

"My golf activity has been very limited," he said. "I can chip and putt really well and hit short irons very well, but I haven't done any long stuff seriously.

"I'm still working. I'm still working on the walking part. My foot was a little messed up there about a year ago, so the walking part is something that I'm still working on, working on strength and development in that.

"It takes time. What's frustrating is it's not at my timetable. I want to be at a certain place, but I'm not. I've just got to continue working.

"I'm getting better, yes. But as I said, not at the speed and rate that I would like.

"You add in the age factor, too. You just don't quite heal as fast, which is frustrating."
