Ireland's Padraig Harrington has withdrawn from the US PGA Championship, to be held in Harding Park, California next week.
In 2008, Harrington became the first European since Tommy Armour in 1930 to win the US PGA, but he hasn't played in America since the tour resumed during the coronavirus pandemic.
His place in the field will be taken by American Talor Gooch.
2018 Open champion Francesco Molinari will also not compete in the event, joining Lee Westwood on the sidelines.
Rory McIlroy, Shane Lowry and Graeme McDowell are all set to tee it up next Thursday.
The trio are currently playing in the World Golf Championship St Jude Invitational in Memphis.
The US PGA Championship was originally scheduled for May before being postponed.
It is the first of three majors that will take place this year. The others will be the US Open, at Winged Foot in New York in September, and the Masters at Augusta in November.
The 2020 Open Championship at Royal St Georges was cancelled, but it will be held there next July.
Harrington's primary disruption this year was related to the Ryder Cup, as he's the current captain of the European Team. The matches which were scheduled for Wisconsin in September will now be staged in September of 2021.
