Tennis superstar Serena Williams is reported to be resting after recently undergoing two separate major surgeries at a Los Angeles hospital.

According to People Magazine, Williams’ spokesperson Nicole Chabot confirmed on Feb. 2 that the 29-year-old, 13-time Grand Slam champion under went “emergency treatment” on Feb. 28 for a hematoma that developed as a result of her being treated for pulmonary embolism, a condition that caused a blood clot to form in her lungs.

Williams, who was already sidelined from tennis action due to a foot injury, stated to the media that her pulmonary embolism is “extremely hard, scary and disappointing.”

“I am doing better. I’m at home now and working with my doctors to keep everything under control. I know I will be OK but am praying and hoping this will all be behind me soon,” said Williams, whose condition may keep her away from tennis for an extended period of time.

“While I can’t make any promises now on my return, I hope to be back by early summer. That said, my main goal is to make sure I get there safely.”

According to Chabot, Williams had just attended the Elton John AIDS Foundation Academy Awards Viewing Party on Feb. 27 before being diagnosed with pulmonary embolism during a doctor’s appointment for her injured foot.

“Thankfully everything was caught in time,” Chabot said. “With continued doctor visits to monitor her situation, she is recuperating at home under strict medical supervision.”
