The ref is Paul Tierney from Lancashire.
And it's the second time refing the Millers this season for Paul, in what is his first season refereeing at Football League level.
Paul took charge of the Millers game at Cheltenham in September.
The 1-1 draw was a painful afternoon for Rotherham caretaker manager Steve Thornber who saw his side utterly dominate the first half but fail to kill off Town after the interval.
The Millers had dominated from the off with Tom Pope, three times, Dale Tonge and Ellison all going close before the visitors took the lead.
Who else but Adam Le Fondre finally broke the deadlock from close range after Cheltenham goalkeeper Scott Brown spilled a corner in first-half injury-time. Julian Alsop scored a crucial equaliser six minutes from time to rescue Cheltenham.
Two bookings that day Low for Cheltenham and Law for Rotherham.
This season's stats for Paul are:
Matches 9, Yellow Cards 21, Red Cards 2.
Running the lines will be: Stephen Ross along with Lee Metcalf, both from Lancashire.
The Fourth Official is David Coote from Nottinghamshire.
