Simona de Silvestro withdrawn from IndyCar Iowa race
Last Saturday, de Silvestro's car made contact with the SAFER barrier on the exit of turn four, in addition to the inside wall of the track. De Silvestro was sent to Froedert hospital, where she was later released.
What followed was a series of medical evaluations throughout the week. The following is a statement from INDYCAR regarding those check-ups:
"Upon evaluation Sunday morning at Milwaukee, Simona had no physical signs of a concussion after the neurological exam and didn't report any post-concussion symptoms to the INDYCAR medical team so she was cleared to drive. After taking 11 laps in the car, Simona returned to the care center reporting post-concussion symptoms. Physical and emotional stress can bring out post-concussion symptoms.
To be cleared to drive after a concussion, a driver must pass the IMPACT Test and INDYCAR Medical evaluation. Simona passed the IMPACT Test on Wednesday but was still exhibiting post-concussion symptoms when evaluated by INDYCAR Medical on Friday at Iowa so she has not been cleared to drive. She will be re-evaluated at Toronto."
