Tony Stewart and Ryan Newman have wrecked during the final Daytona 500 practice, tearing up Stewart-Haas Racing's two cars before Sunday's season-opening race.
Newman, the defending Daytona 500 winner, lost his right rear
tire Saturday and his car spun out of control. Stewart, his car
owner, was trailing tightly around Daytona International Speedway
and couldn't avoid running into him.
Newman's crew has pulled out a backup car. Newman wrecked two
other cars during practice.
Stewart was scheduled to start fifth in the Daytona 500. He may
consider a move to a backup car, which would force him to start at
the back of the field.
