"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.Back issues have plagued Woods in 2014. He had to withdraw due to back pain during the final round of the Honda Classic March 2nd. He was visibly bothered a week later at the World Golf Championship at Doral.
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."
