Scott Miller and Richard Childress Racing have parted ways.

Miller had served as director of competition since 2008 for RCR, whose drivers are Clint Bowyer, Jeff Burton, Kevin Harvick and Paul Menard. Miller also worked as crew chief during his second tenure, which began in 2003.

After a short sabbatical, sources said Tuesday, Miller will fill a similar role at Michael Waltrip Racing.

Kent Day will serve as interim director of competition for RCR until a permanent replacement can be found.

Miller initially worked with RCR from 1997 to 1999. The 54-year-old Anaheim, Calif., native started his racing career in open wheel before leaving Indianapolis for North Carolina in 1994.
