Gavin Ward from Surrey.
Seen as one of the more stricter refs on the circuit Gavin isn't shy with the cards and sent off Kari Arnason the last time he reffed a Millers match, the 3-0 FA Cup defeat at Aldershot.
Danny Hylton, then a Shots player, bagged a hat-trick and was also sent off for elbowing Jason Taylor.
So far this season Ward has dished out 85 yellows and 6 red cards in just 28 matches.
Running the lines are Mr. M. Astley (Manchester) and Mr. S. Meredith (Nottinghamshire).
The fourth official is Mr. M. Jones (Nottinghamshire).
