"I personally called Arnold today to tell him that, sadly, I won't be able to play in his tournament this year. I would like to express my regrets to the Orlando fans, the volunteers, the tournament staff and the sponsors for having to miss the event. Unfortunately, my back spasms and the pain haven't subsided.

It's too early to know about the Masters, and I will continue to be evaluated and work closely with my doctors. I feel badly that I won't be able to play in this great tournament this week."
