Andy Woolmer from Northamptonshire.
We've already seen Andy once this season as he took charge of the 5-2 thrashing at Bristol Rovers back in October. The Millers were in the middle of a 12 game winless run at the time. Jason Taylor and Danny Schofield were on the scoresheet that evening.
Three players were also shown yellow and Guy Branston was sent for an eatrly bath for a two footed lunge, having only just re-joined the club on loan from Bradford.
So far this season Woolmer has dished out 87 yellow cards and six reds in his 25 games, 3 of those reds coming in Brighton's 1-0 win over Leicester 3 weeks ago.
Running the lines are Mr. C. Hicks (Surrey) and Mr. T. Robinson (West Sussex).
The fourth official is Mr. S. Rubery (Essex).
