CANANDAIGUA, 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 darkened dirt track and was trying to confront Stewart when he was struck Saturday night.
NASCAR driver Tony Stewart struck and killed a sprint car driver walking on the track during a race in upstate New York on Saturday evening.
Authorities have launched a non-criminal investigation. Stewart is said to be cooperating.
The victim, who was not identified by authorities, was pronounced dead at hospital in Canandaigua Saturday night.
Videos of the crash posted to YouTube appeared to show driver driver Kevin Ward Jr. walking toward Stewart's car before being hit and hurtled into the air.
Fan Michael Messerly says it appeared Stewart hit a driver who was walking on the track after they collided on a prior lap. He says Stewart did not appear to be injured.
A spokeswoman at Thompson Health says one patient is being treated from Saturday night's crash at Canandaigua Motorsports Park. She would not give further details.
The track canceled the remainder of the Empire Super Sprints slate.
Stewart was scheduled to start Sunday at Watkins Glen International.
