Doral - Americans Bubba Watson and Ben Crane and South African Tim Clark have pulled out of the WGC-Cadillac Championship starting on Thursday, officials said.
Watson, ranked 15th in the world, said he had been feeling ill and short of energy and after trying out on the practice range he withdrew shortly before the tournament was due to begin.
Clark has been battling against tendinitis in his right elbow and has not played since tying for second place at the Sony Open in Hawaii seven weeks ago.
Crane pulled a rib muscle during his third-round defeat at the WGC-Accenture Match Play Championship two weeks ago.
