Paul Casey has told tournament officials he will not be competing next week in the World Golf Championships-Accenture Match Play Championship at the Ritz-Carlton Golf Club in Marana, Ariz.
The Englishman, who was the runner-up in 2009 and 2010, dislocated his shoulder in a snowboarding accident last month. Casey, who is ranked 23rd in the world, hopes to be ready to make his 2012 PGA TOUR debut at the World Golf Championships-Cadillac Championship in three weeks.
Casey will be replaced by South Africa's George Coetzee, who is ranked No. 66 in the world. Coetzee will be making his World Golf Championships debut.
The field for the Accenture Match Play Championship is comprised of the top 64 available players in the world rankings. World No. 11 Phil Mickelson has already said he won't play due to a family vacation so he was replaced by No. 65 Ernie Els.
Should another player withdraw Ryan Moore would be the next player in the field.
