Canadian Graham DeLaet withdrew from the PGA Championship on Monday as he continues to struggle with an injured left thumb.
The native of Weyburn, Sask., withdrew from the RBC Canadian Open on July 24 because of the injury.
"So disappointed that I can't tee it up at the PGA. Need some time for my body to heal. I plan on being back and ready for a playoff run," said DeLaet from his verified Twitter account.
DeLaet had high hopes for the PGA Championship and had been practising, telling The Canadian Press his thumb was at "90 per cent" on Thursday.
Sean O'Hair will take his place in the field.
David Hearn and Nick Taylor are the only Canadians left in the field at the PGA Championship.
The event begins Thursday.
Note to readers: This is a corrected version of an earlier story. The PGA Championship begins Thursday, not Tuesday, as previously stated.
