Nine laps into Saturday's final practice session for the Kobalt Tools 500, Greg Biffle smacked the Turn 4 wall at Atlanta Motor Speedway with right side of his #16 Ford.
Forced to a back-up car, Biffle will give up his 13th starting position for Sunday's race and take the green flag from the rear of the field.
Biffle, currently sixth in the NASCAR Sprint Cup standings, returned to the track in the back-up car late in the session but turned enough laps to feel optimistic about the race.
"To be honest with you, it couldn't have gone better," Biffle said. "I got out (on the track) with six minutes to go. The car drove really, really well, and it drove better than my old (primary) car for that short run. I think we're going to be pretty good."
As he sat in the back-up waiting to return to the track, Biffle pointed out that Kyle Busch had scraped the wall about 18 times in winning the spring race at Atlanta two years ago.
"I just hit it in the wrong place," Biffle said. "I just got a little bit loose running the top. The back end touched the wall and sucked the nose over, right where they stopped the SAFER barrier. I hit right in the worst spot, where the wall was kinked out. I just killed the car."
