Day had an MRI on Wednesday in Miami. While the results were negative, the doctor recommended rest if possible.
“My left thumb was bothering me at the Accenture Match Play Championship and the pain continued here this week,” said Day in a statement. “I had an MRI yesterday here in Miami with Dr. Lee Kaplan. Fortunately, the MRI was negative, but the doctor prescribed rest if I was unable to play today. My plan is to rest for a couple of weeks.
“I’m sorry to miss the Cadillac Championship; it looks like it’s going to be a great event.”
Day plans to stay and try to practice at Doral through the weekend and see if he feels healthy enough to play next week in Tampa.
