Ammon News - The Australian, who won the title in 2019, decided to call time on her second-round match in the early stages of the second set as a result of an injury to her left hip.
World No 1 Ashleigh Barty has withdrawn from the French Open due to injury.
The 2019 champion was forced to retire due to an issue with her left hip, when she was 6-1 2-2 down against Magda Linette in the second round.
Barty, who had been pushed to three sets by the world No 70 Bernarda Pera in the first round, had made it clear that she was entering the contest not being 100 per cent fit.
The Australian said that she would "give it a crack no matter what" however, the treatment she received at the end of the first set, clearly did not do enough to alleviate her discomfort.
With the Wimbledon Championships starting in 25 days, attention will quickly turn to whether or not the world No 1 will be fit to take part and compete on the grass.
It's a Grand Slam that she has not won, with her best result - reaching the Round of 16 - coming in 2019 off the back of her Roland Garros title.
Linette, who will continue on in the 2021 edition of the French Open, will now face the 25th seed Ons Jabeur in the third round.
