Mark Martin has the most Nationwide victories at Atlanta with three, followed by Matt Kenseth and Jeff Burton with two each. Kenseth won last year's race there, but will not defend his title this weekend.

Forty-eight teams are on the preliminary entry list for the Degree V12 300. Dale Earnhardt Jr., Ryan Newman and Kasey Kahne are among the 15 Sprint Cup regulars expected to compete.

Camping World Truck Series

Lucas Oil 200 - Iowa Speedway - Newton, IA

For the second week in a row, the Camping World Truck Series runs at a racetrack that is a newcomer to the schedule. The series ran at Chicagoland for the first time last Friday.

Ron Hornaday Jr. currently holds a 220-point lead over Matt Crafton. It's a good thing for Hornaday that Kyle Busch is not competing in Saturday night's race at Bristol. Busch has taken the No.51 Billy Ballew Motorsports Toyota to victory lane in the last two truck events. He ended Hornaday's series record five-race winning streak at Bristol.

Brian Ickler will drive the No.51 truck at Iowa.

Iowa is the fifth of six short tracks on the series schedule this year. The Nationwide Series ran at the 0.875-mile track one month ago.

"It looks like Richmond, but every track has its own style," Hornaday said. "From what I understand talking with Kevin [Harvick] and Cale [Gale], who drove the Nationwide car there earlier this year, the track is developing some bumps that you really have to get over in order to have your vehicle handling well."

Hornaday holds the series record for most wins on short tracks. Twenty of his 45 career victories have come on tracks less than one mile in length.

Crafton has also performed well on short tracks this year, finishing fifth at Memphis and second at Bristol. With nine races to go in the season, Crafton is far from giving up on his championship hopes.

"We're definitely still in this thing," Crafton said. "There's a lot of racing left. We've all seen examples of how points can swing one way or another pretty quickly, so there's no reason to think it won't happen for us."

Austin Dillon will make his truck debut at Iowa, as Richard Childress Racing returns to the series for the first time since 1999. Dillon, the grandson of team owner Richard Childress, will drive the No.3 RCR Chevrolet. Mike Skinner drove the No.3 for Childress during the inaugural truck season in 1995. Skinner won the title that year.

"RCR was fortunate enough to win the first race and the first championship in the NASCAR Camping World Truck Series in 1995, with Mike Skinner driving the No.3 Chevrolet, so it's great to see the No.3 truck back on the track," Childress said.

Dillon competed in the Nationwide race at Iowa, finishing 28th. He also has two starts in the NASCAR Camping World Series East and one start in the ARCA Re/Max Series there.

"I couldn't have picked a better race track to make my debut," Dillon said. "I've raced at Iowa Speedway three times this season and feel confident heading back. We think we can be competitive during the race once I get a feel for how the truck handles during the practice sessions. Overall, our goal is to learn as much as we can during the race, earn a solid finish and, more importantly, have fun."

Thirty-six teams are on the preliminary entry list for the Lucas Oil 200, making a full field for the event.
