NASCAR confirmed Wednesday that John Darby, who formerly oversaw the Sprint Cup garage, will be leaving the series soon. No reason was given.
Darby had been working on special projects most recently for NASCAR. He served as the Sprint Cup Series director from 2002-13 before Richard Buck took over in 2014. NASCAR initially announced that Darby was leaving his position as Cup director in 2010, but it took four years to replace him.
Darby replaced Gary Nelson as Cup series director in 2002. Darby was the director of what is now the Xfinity Series from 1999-2001 before moving to Cup.
