Former world number one Tiger Woods is "hopeful" of a return for the Masters but will miss next week's Arnold Palmer Invitational.
The 14-time major winner is taking an indefinite break from the game having described this year's performances as "unacceptable for tournament play".
"I've put in a lot of time and work on my game and I'm making strides," said Woods, 39.
Woods added that he won't return until he can "compete at the highest level".
He has won the Arnold Palmer Invitational, held in Orlando, Florida, eight times in his career.
In a statement on his official website, Woods said: "I spoke to Arnold today and told him that I will not play in his tournament this year. I'm sorry I won't be in Orlando next week, but I know it will be a really successful event.
"I hope to be ready for the Masters, and I will continue to work hard preparing for Augusta."
The Masters in Augusta, which Woods has won four times, begins on 9 April.
