'I have undergone almost two months of inpatient therapy and I am continuing my treatment. Although I'm returning to competition, I still have a lot of work to do in my personal life.
'When I finally got into a position to think about competitive golf again, it became apparent to me that the Masters would be the earliest I could play. I called both Joe Lewis and Arnold Palmer and expressed my regrets for not attending the Tavistock Cup and the Arnold Palmer Invitational. I again want to thank them both for their support and their understanding. Those are fantastic tournaments and I look forward to competing in them again.
'I would also like to thank the Augusta National members and staff for their support. I have deep appreciation for everything that they do to create a wonderful event for the benefit of the game.'
Woods has won the green jacket four times.
