WATKINS GLEN, N.Y. (AP) -- Tony Stewart will not race Sunday following the death of a sprint car driver who was struck and killed by Stewart at an upstate New York dirt track.
Greg Zipadelli, competition director for Stewart-Haas Racing, said the three-time NASCAR champion "feels strongly" he should not race at Watkins Glen following Kevin Ward Jr.'s fatal accident.
Regan Smith will replace Stewart in the car.
Ward had climbed from his car on the dirt track after a collision and was trying to confront Stewart when he was struck Saturday night.
A video of the crash at Canandaigua Motorsports Park showed driver Kevin Ward Jr. stepping toward Stewart's car before being hit and thrown 50 feet. It is unconfirmed whether or not Stewart revved his engine and lost control of his race car before striking Ward.
