'I'm feeling good after taking all this time off, and I'm feeling healthy,' Duval said from his home in Denver. 'But I feel like I need to give it more time and make sure I'm healed.'
He has not played on the PGA Tour since he missed the cut in Las Vegas last October. He withdrew with a sore back during the first round of the Dunlop Phoenix in Japan in November.
Duval said he has a 'decent idea' when he might return to the PGA Tour, although he declined to say.
It will be the first time he has not played the Masters since he first qualified in 1996, and while he has gone six months without playing a PGA Tour event, it was difficult to pass on Augusta National.
