Phil Mickelson suffered a minor shoulder injury during a workout in the gym and will miss the LIV Golf season opener in Saudi Arabia this week.
Mickelson, 54, made the announcement Monday on social media.
Ollie Schniederjans will replace Mickelson in the LIV field this week, joining the captain's HyFlyers team at LIV Golf Riyadh beginning Thursday. The HyFlyers are still looking for their first team victory.
Mickelson said he expects to compete next weekend at LIV Golf Adelaide at The Grange Golf Club in Australia.
"I'm definitely disappointed that I will miss the season opener, but I look forward to playing in Adelaide," he said.
Schniederjans, a 31-year-old who grew up in Georgia, narrowly missed earning a full LIV card at the LIV Golf Promotions event late last year but gained the right to play in the 10 events in The International Series in 2025.
He capitalized on that Sunday, winning The International Series India by four strokes over U.S. Open champion and LIV star Bryson DeChambeau. Another stroke back in third place sat a pair of LIV players, JoaquÃn Niemann and Abraham Ancer.
