Padraig Harrington has withdrawn from next week's PGA Championship.
The first major of a rescheduled golf calendar takes place from August 3–9 at the TPC Harding Park in San Francisco.
Harrington has revealed he will not travel to the United States for the tournament due to the Covid-19 pandemic.
He said on Facebook: "After much deliberation, I have decided not to travel to next week's PGA Championship.
"As Covid-19 currently looks to be under control in Ireland, I am taking the prudent approach by following the guidelines and reducing the risk as much as possible by staying at home.
"I'm sure I'll be watching every shot on TV with great interest and hopefully I'll have many more years to play in the PGA Championship."
Former Open champion Francesco Molinari is also understood to have withdrawn from the year's first major at TPC Harding Park in San Francisco.
Lee Westwood and Eddie Pepperell have also made the decision not to travel to San Francisco.
Harrington and Molinari have been replaced in the field by Talor Gooch and Troy Merritt.
