Five of the top 20 players in the world rankings, including Lexi Thompson and Danielle Kang, will not play in the Evian Championship.
The Evian, the fourth major of the LPGA Tour season, is played annually in France and is scheduled for July 22-25.
This year's Tour program packs in two majors – the Evian and the Women's Open at Carnoustie – with the Tokyo Olympics in the span of a month from July 22 to August 22.
The deadline to commit to the event was Tuesday, with big names Kang and Thompson not on the official list.
Kang and Thompson are two of the four women who'll compete at the Olympics for Team USA, so the tight schedule may have influenced their decision.
Also taking time off from the Tour to prepare for the Olympics are Australia's Hannah Green and Shanshan Feng of China.
Japan's Nasa Hataoka, the runner-up at last month's US Women's Open, is also missing from the Evian field.
But all three of this season's major champions – Thailand's Patty Tavatanakit (ANA Inspiration), Philippines' Yuka Saso (US Open) and World No.1 Nelly Korda (Women's PGA Championship) – have committed to play in France.
So has Korda's sister Jessica, the final member of the American Olympic team after her sister, Thompson and Kang.
World No.2 Jin Young Ko of South Korea is the 2019 champion. The major was not contested in 2020 due to the COVID-19 pandemic.
