Bubba Watson among 3 withdrawals
Clark has not played since his runner-up finish in the Sony Open at the start of the year because of an elbow injury. Watson cited an illness, while Crane is coping with a bad back.
Crane first felt recurring back pain at the Match Play Championship two weeks ago, when he lost in the third round to Miguel Angel Jimenez. Watson also starred at the event, reaching the semifinals.
