Grimsby legend John McDermott has been appointed as a coach at the club's football academy.
McDermott is Grimsby's record league appearance maker
He will join ex-Mariner Gary Childs in looking after the young players coming through the ranks at Blundell Park.
McDermott, 38, retired this summer after making a record-breaking 646 league appearances for the Mariners over a period of 20 years.
In June he applied for the manager's job at Boston, following their relegation from the Football League.
