Former Bury manager Chris Casper has been appointed as Grimsby's new first-team coach.
The former Manchester United trainee became one of the youngest ever league managers in October 2005 when he took the reigns at Bury aged just 30.
He helped them to avoid relegation that season but after a run of poor results left the club in January 2008, joining Bradford as their youth team coach five months later.
Casper will begin his new role immediately.
