Spaniard Paula Badosa has withdrawn from the U.S. Open as she recovers from a back injury, tournament organisers announced on Friday.
World number 12 Badosa has suffered a string of injuries, including a chronic lower back issue that even had her considering retirement.
Last month, the former world number two announced she would be sidelined for a few weeks due to yet another back injury.
Badosa last played at Wimbledon, where she suffered a first-round defeat. She then revealed she had suffered a tear in her psoas, the muscle which connects the lower back to the top of the leg.
With Badosa’s withdrawal, Switzerland’s Jil Teichmann will move into the main draw of the U.S. Open, where singles action begins on August 24.
Badosa has also had to withdraw from the tournament’s new mixed doubles event, in which she had been expected to partner Britain’s Jack Draper.
