The last time Grimsby and Doncaster met in the league, a John Marquis hat-trick saw Rovers to a 5-1 victory at Blundell Park: the penultimate result en route to securing their promotion destiny in 2016-17.
This short trip east might not be quite as memorable as that one for Donny fans, though the first two league performances under Danny Schofield - a 1-0 defeat by and victory over Stevenage and Gillingham respectively - offer encouragement.
The League Two play-off chaser’s FA Cup outing holds less encouragement, with defeat by the same scoreline to National League North leaders King's Lynn - but it was a different story for Grimsby.
