Three-time NASCAR champion Tony Stewart cancelled out of a previously scheduled dirt track race in Indiana.

Stewart's car struck and killed driver Kevin Ward Jr. during a dirt track event Saturday night in upstate New York.

Plymouth Speedway released a statement Monday announcing that Stewart will not compete in this Saturday's race.

"We at Plymouth Speedway extend our deepest condolences and prayers to the family of Kevin Ward, Jr. and thoughts and prayers to Tony Stewart and his family," the statement read. "Tony Stewart will NOT be racing at Plymouth Speedway this Saturday."

Stewart withdrew from Sunday's NASCAR Sprint Cup race at Watkins Glen, N.Y., hours after the accident at Canandaigua Motorsports Park.

Ward and Stewart tangled, sending Ward's car into the retaining wall. Ward then climbed out of his car and walked toward cars still moving at a speed of about 40 mph around the race track. One car that reached Ward before Stewart was able to miss him, but even though Stewart swerved to miss, Ward was hit by Stewart's right-rear tire and thrown about 30 feet. Ward was dead by the time his ambulance reached an area hospital.

The next NASCAR race is this Sunday in Michigan. Stewart has not announced if he will race in that event.
