Before she collapsed on court during her second-round match, Victoria Azarenka hit her head while warming up in the gym, she said in a statement. She was diagnosed with a mild concussion.
Full statement: "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."
