Tennis star Serena Williams was recuperating at home Wednesday after emergency treatment for swelling from a blood clot in her lungs.

"Serena did indeed suffer from a pulmonary embolism last week, and the hematoma was another unexpected scare. Thankfully, everything was caught in time. With continued doctor visits to monitor her situation, she is recuperating at home under strict medical supervision," Williams' rep, Nicole Chabot, told

On Monday, Williams, 29, checked into Cedars-Sinai hospital in Los Angeles with a hematoma that was a result of her earlier treatment.

The younger sister of Venus Williams, she last played when she won Wimbledon for the fourth time last July. She subsequently cut her right foot on broken glass at a restaurant, and since then her return has been delayed by complications with the injury.

"This has been extremely hard, scary, and disappointing," Williams said in a statement. "I know I will be OK, but am praying and hoping this will all be behind me soon. 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."
