US Open champion Naomi Osaka has pulled out of the French Open, which is scheduled to start on 27 September.
On Saturday, the Japanese player won her second US Open, and third Grand Slam title, with a 1-6 6-3 6-3 victory over Victoria Azarenka in New York.
"My hamstring is still sore so I won't have enough time to prepare for the clay. These two tournaments came too close to each other for me."
The 22-year-old had her left hamstring wrapped in tape when she beat Azarenka in the final at Flushing Meadows.
The world number three, who won the Australian Open in 2019, has never gone beyond the third round at Roland Garros.
