Simon Hooper from Wiltshire.
Fresh from the fourth official duties in the Coventry and Preston 4-4 draw on Sunday, this will be a first Millers match for Simon since February 2011 when he sent off debutant Callum Kennedy in the 2-1 defeat at Oxford. Somehow we've managed to avoid him since then.
Last season Hooper reffed 39 games in all competitions, showing 105 yellows and 5 red cards.
Running the lines at Villa Park are Mr. D. Leach (Oxfordshire) and Mr. A. Nunn (Wiltshire).
The fourth official is Mr. B. Malone (Wiltshire).
