Tiger Woods has admitted he may never return to competitive golf.
Speaking ahead of this week's Presidents Cup where Woods will assist United States captain Steve Stricker, the 14-time major champion doubted whether he could work as a captain's assistant at this week's Presidents Cup because riding in a golf buggy "hurt too much".
The 41-year-old has had multiple back operations in recent years and withdrew from his last tournament in January with back spasms.
Woods said last week that he had been hitting 60-yard shots but had no date in mind for a return to competitive action.
Asked whether it was possible he may never compete again, he said: "Yeah, definitely. That's going to take time to figure out what my capabilities are going forward - and there's no rush."
He might not even be able to fulfil his duties as an assistant captain for the Americans clash versus the Internationals at Liberty National this week.
"I didn't know if I was going to be able to be here, because I couldn't ride in a cart," he said. "The bouncing hurt too much.
"That's all gone now, which is fantastic.
"I'm still training, I'm getting stronger. But I certainly don't have my golf muscles trained because obviously I'm not doing anything golf related."
Woods last had surgery in April, which followed his withdrawal from the Dubai Desert Classic in January.
