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 darkened dirt track and was trying to confront Stewart when he was struck Saturday night.
