Rob Lewis from Shropshire.
Some of you may remember Lewis as the linesman who didn't see Man Utd keeper Roy Carroll's blunder when the ball travelled a good yard over the line after a long range shot from Spurs' Pedro Mendes at Old Trafford a few years back.
Less famously, he's reffed the Millers against Northampton twice in the past two seasons, the 2-2 draw at Don Valley last campaign and earlier this season in the 1-1 draw at Sixfields.
Running the lines will be Mr. A. Greenwood (North Yorkshire) and
Mr. W. Porter (Lincolnshire).
The fourth official is Mr. D. Benton (South Yorkshire).
