Don't look for defending Daytona 500 winner Jimmie Johnson to take many chances in Thursday's qualifying race.

Johnson already wrecked one car in the exhibition Sprint Unlimited last week and really likes the Chevrolet his team has prepped and ready for "The Great American Race" on Sunday.

So Johnson was one of a handful of drivers who turned few laps in the two practice sessions Wednesday.

He says he doesn't want to risk wrecking his car, and Hendrick Motorsports having to call for the backup to be sent from North Carolina.
