US golf star Phil Mickelson will also not be at the PGA Championship next week in Tulsa/Oklahoma. The organizer announced this on Friday.
The 51-year-old, who already missed the Masters in April, will not be able to defend his title.
Last year, Mickelson won the tournament at the course on Kiawah Island in South Carolina and was crowned the oldest major winner in golf history. It was the sixth major title of his career.
At the beginning of the year, Mickelson caused discussions with statements about Saudi Arabia and the PGA and announced a longer break.
