James Hinchcliffe has a concussion from being hit in the head with debris in the inaugural Grand Prix of Indianapolis.
Hinchcliffe suddenly pulled off the road course at Indianapolis Motor Speedway following a restart Saturday and could be seen holding his head with both hands as he exited his car. The Canadian was taken from the track on a stretcher and transported to a hospital.
IndyCar said Saturday night he had been released from the hospital after a CT scan on his head and neck. He must be medically cleared by IndyCar to drive, and the waiting time is usually a minimum of seven days.
IMS opens Sunday for practice for the Indianapolis 500. Qualifications begin next Saturday and the race is May 25.
