Joe Gibbs Racing will replace Kyle Busch's crew chief after this weekend's race at Talladega Superspeedway. Steve Addington is out after 12 victories in 68 races running Busch's team. He'll be replaced by Dave Rogers, a crew chief for JGR in the Nationwide Series. Addington leaves after a disappointing season for Busch. He won four races but missed a spot in the Chase for the Sprint Cup championship by just eight points.
