2010 U.S. Open: Victoria Azarenka Released From Hospital

U.S. Open No. 11 Victoria Azarenka of Belarus, who collapsed on the court in her second-round match Wednesday morning, has been released from the hospital with a diagnosis that dovetails with her earlier "headache-like symptoms": She apparently sustained a mild concussion during an earlier training session.

Azarenka is said to be resting at her hotel, and has released a statement detailing the events that led to her collapse:

I was warming up in the gym prior to my match against Gisela Dulko when I fell while running a sprint. I fell forward and hit my arm and head. I was checked by the medical team before I went on court, and they were courtside for monitoring. I felt worse as the match went on, having a headache and feeling dizzy. I also started having trouble seeing and felt weak before I fell. I was taken to the hospital for some medical tests and have been diagnosed with a mild concussion.
