Serena Williams, 29, was seen at Cedars-Sinai Medical Center in Los Angeles on several occasion in the past week. Williams’s rep, Nicole Chabot, confirmed the athlete’s heath status to PEOPLE.

“Monday Serena Williams underwent emergency treatment at Cedars for a hematoma she suffered as a result of treatment for a more critical situation,” the rep says in an exclusive statement.

“Last week, Serena suffered from a pulmonary embolism [a blood clot in the lungs] which was discovered upon her return to L.A. She had been in New York for doctor appointments for the ongoing issues with her foot.”

“Doctors are continuing to monitor her situation closely to avoid additional complications.”
