Four-time champion Serena Williams withdrew from the upcoming Italian Open, citing the Achilles injury that bothered her in a loss to Victoria Azarenka in the U.S. Open semifinals, organizers at the Foro Italico announced on Saturday.
Williams took a medical timeout for a tape job on her Achilles during her three-set loss on Thursday.
The Italian Open, which was rescheduled from May due to the coronavirus pandemic, begins on Monday.
"I regretfully must withdraw from the [Italian Open] due to an Achilles strain," Williams said. "I'm so humbled by the continuous support from my fans in Rome and I look forward to making my return soon."
