Injured Paul Casey will not return for the Match Play championship.
His spot in the 64-man field next week in Arizona will be taken by George Coetzee.
Casey injured his shoulder while snowboarding over the holidays. He hopes to return the second week in March for the Cadillac Championship at Doral.
Phil Mickelson already said he won't be playing in Match Play because his kids are out of school and he's going on a family vacation. He won at Pebble Beach last weekend.
Coetzee will play top-ranked Luke Donald, baring other withdrawals.
