Serena Williams bows out of upcoming Italian Open with Achilles injury
U.S. Open finalists Dominic Thiem, Alexander Zverev have withdrawn on men's side
Four-time champion Serena Williams withdrew from the upcoming Italian Open citing the Achilles issue that bothered her in a loss to Victoria Azarenka in the U.S. Open semifinals, organizers at the Foro Italico announced Saturday.
Williams took a medical timeout for a tape job on her Achilles during her three-set loss on Thursday.
"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."
The Italian Open, which was rescheduled from May due to the coronavirus pandemic, begins Monday.
Azarenka remained entered for Rome.
