Felix Rosenqvist was involved in a violent crash in Saturday's IndyCar race at the Detroit Belle Isle street circuit.
Rosenqvist's car went head-on into a tire barrier after the throttle appeared to have stuck on his car. The impact launched tires over the chainlink fence behind the wall of tires and Rosenqvist's car was lodged pointing skyward.
IndyCar safety workers delicately removed Rosenqvist from the car and he was placed on a stretcher after he was extricated. He was then loaded into a waiting ambulance while wearing a neck brace. His team said he was being taken to a hospital for a thorough evaluation.
