Nigel Miller from Co. Durham.
Nigel made the National list of assistant referees in 1996, after starting refereeing in 1989, and was promoted to the National List of referees in 2003.
This will be Nigel's second visit this season to Don Valley; back in September he was in charge of the Millers game with neighbours Chesterfield.
In what had been a turbulent week with Mark Robins being put on gardening leave and John Breckin being put in temporary charge for the game, supporters wondered how the players would respond.
The match didn't look as though it was going to lift supporters spirits when Miller gave the Spireites the advantage giving a penalty after consulting his linesman, and deciding Green had brought down Derek Niven in the box, Jamie Lowry stepped and converted the spot kick.
The second-half saw the players respond with a fight back with goal's from Harrison, Le Fondre and Ellison giving the Millers a 3-1 victory.
This season in 26 Games Nigel has issued 61 Yellow and 8 Red cards, ouchie!!
Running the lines will be Mark Astley (Manchester) along with Jason Whiteley (West Yorks)
The Fourth Official is Darren England (South Yorks)
