#18-Kyle Busch, who leads the Sprint Cup Series standings, will run that series' events at Pocono Raceway, the Pocono 500 on Sunday afternoon in addition Busch also plans on being at Texas Motor Speedway for Friday night's Craftsman Truck Series race, the Sam's Town 400. Then, on Saturday night, he'll be in the Nationwide Series at Nashville Superspeedway for the Federated Auto Parts 300 presented by Dollar General. This is unprecedented to say the least. No driver has ever attempted to run in all three NASCAR national series on one weekend at three different tracks. Due to the intense travel challenges, Busch will take part in only one qualifying session this weekend – at Pocono, in the #18 Toyota for Joe Gibbs Racing. At Nashville, Busch will be in the #32 Toyota for Braun Racing. Tennessee native Will Allen will sub for Busch during practice and qualifying. At Texas, Busch will be in the #51 Toyota for Billy Ballew Motorsports, but qualifying and practice in the truck will be handled by J.R. Norris.(NASCAR PR)(6-3-2008)
