The world No. 4 was a surprising WD two weeks ago at Doral, where he pulled out before the start of the first round. Day underwent an MRI in Miami that revealed no damage, but he said he has experienced discomfort since last month’s WGC-Accenture Match Play, which he won. He was spotted at Bay Hill with heavy tape on his left thumb.
It was not immediately clear when, or if, Day will play again before the Masters. He has missed the cut in all three appearances at the Valero Texas Open (2006, 2008 and 2009), and he hasn’t played the Shell Houston Open, scheduled the week before Augusta, since 2011.
The 26-year-old has two top-3 finishes in the past three years at the Masters.
