(USA TODAY) --A race car driver was killed Saturday night after he was struck on the track by NASCAR star Tony Stewart, according to Ontario County (N.Y.) Sheriff Philip C. Povero.
During a sprint car race at Canandaigua (N.Y.) Motorsports Park, driver Kevin Ward Jr. was spun out by Stewart, got out of his car to show his displeasure and then was struck by Stewart's car, sending Ward sliding down the track, fellow sprint car racer Tyler Graves and witness Adam Dulski told USA TODAY Sports.
Povero confirmed the driver was taken by ambulance to Thompson Health and was pronounced dead on arrival.
Stewart's public relations team and NASCAR did not respond to USA TODAY Sports' requests for comment.
"This is an ongoing investigation of an on-track crash," Povero said.
He indicated Stewart was cooperative and there were no charges pending at this time.
