Phil Mickelson has withdrawn from next week's PGA Championship, ensuring the six-time major champion will not be able to defend his title, according to tournament organisers.
Mickelson became the oldest major winner in golf history last year when he won the event - the second major tournament of the year - at Kiawah Island. He has not played since January after taking a break from the sport in the wake of his ill-advised comments on Saudi human rights issues amid the Saudi-backed LIV Golf Invitational Series.
The fallout meant Mickelson missed the Masters for the first time in 28 years and was excluded from the annual champions dinner at Augusta. Mickelson has not been seen publicly since he played in the Saudi International on February 6.
