The tennis star was rushed to the hospital earlier this week where doctors found a pulmonary embolism, or a blood clot in her lung, and hematoma or the pooling of blood under her skin.

Serena thanked her fans for their prayers and well wishes and said while she believes she’ll be able to return to the court early this summer, her main goal is to make sure her health is in order.

This isn’t the first setback Williams has encountered. She hasn’t played a match since last July, when she won Wimbledon. After that, she injured her foot by stepping on a piece of broken glass in a restaurant.
