Michael Lewis has been released from hospital following his high-speed crash in Formula 3 European Championship qualifying at Brands Hatch, but will not race.
The 22-year-old American was diagnosed with a mild concussion after being taken to hospital in London on Friday, but received no serious injuries and no broken bones.
Although the Mucke Motorsport driver plans to return to the track to watch Saturday's races, doctors did not pass him fit to race.
