Kyle Busch in at Talladega, out at Kansas

The NASCAR Sprint Cup Series is at Talladega Superspeedway, the Craftsman Truck Series is at Kansas Speedway and Kyle Busch will not be able to be in both places for the races.
Busch has been leading the Truck Series standings since winning the race at Auto Club Speedway in Fontana in February. But he won't be the No. 51 Toyota for Billy Ballew Motorsports when the truck races Saturday in Kansas.
Shane Sieg, a 25-year-old from Georgia, is entered in the Kansas race for Ballew, who can still maintain his lead in the Truck Series owners standings.
Busch is expected to be back in the No. 51 truck for the May 16 race at Lowe's Motor Speedway in North Carolina.
“With Kyle’s schedule at Joe Gibbs Racing this weekend, there was no way he could make the race in Kansas. We looked at all the scenarios but it just wasn’t feasible,” Ballew said. “Shane has driven for us before and is familiar with the equipment. We hope to leave Kansas still leading the owners’ points and know Kyle can make up some ground in the drivers’ points when we race at Lowe’s."
Sieg has 27 career Truck Series starts since 2003 and has a career-best finish of eighth, which came at the Milwaukee Mile. He drove Ballew's No. 15 truck three times last season, his best finish coming at New Hampshire International Speedway, where he was 10th.
“It’s a great opportunity to get back behind the wheel,” Sieg said. “I know I have big shoes to fill but I just want to bring a good finish home to keep Billy as the team owner point leader.”
