The Tyne and Wear-based official will travel to the Sands Venue Stadium for his fifth game of the campaign and his second involvement in this season's EFL Trophy.
His first game of the campaign was the 1-1 draw between Burton Albion and Accrington Stanley in Sky Bet League One, issuing one caution. His latest game, in which he showed no cards, was Wigan Athletic's 6-1 victory over Liverpool's Under-21s in the EFL Trophy.
He's taken charge of the Iron on 20 occasions in total, most recently in this competition last season when United wonr 2-1 at Grimsby Town thanks to a brace from Kevin van Veen. James Perch was shown a late red card by Haines, but that decision was later overturned by an Independent Regulatory Commission.
Of those encounters involving United, 16 of them have come at the Sands Venue Stadium, so Tuesday will be his 17th visit as the man in the middle. In total, across the 20 games, he's shown 62 yellow cards and one red.
Meanwhile, he's yet to referee the Blue's Under-21s side.
In 2019-20, he took charge of 32 games, issuing 84 yellow cards and eight reds. So far in this campaign, he has officiated in four encounters, showing six yellows and no reds.
On Tuesday, Haines will be assisted by Paul Newhouse and David Avent, while Daniel Middleton has been appointed as the fourth official.
