Man in the Middle vs Lincoln
Robert Jones will be the man in the middle for the local derby, and he has so far whisked 21 yellow cards from his pocket this season, so expect a few at Sincil Bank.
It will be Jones's second consecutive game in League 2 this season, having been in charge of Grimsby's surprise 2-1 win at Accrington Stanley in midweek.
He was to show five yellows in that game.
Jones was last in charge of the Stags in the 1-0 away win at Wycombe last season on good friday in April.
Ken Haycock and Paul Thompson will be his assistants.
