David was involved in Millers action twice last season, firstly the 1-1 draw away at Accrington last September and then the 3-2 victory at Don Valley against Morecambe back in April this year.
After Ryan Cresswell was sent off, a Lewis Grabban brace, the second coming in injury time, gave Steve Evans his first win as Millers manager.
This campaign David has issued 21 yellows and no red cards in his 7 games so far.
Running the lines at Bootham Crescent will be Mr. M. Dwyer (West Yorkshire) and Mr. P. Davison (Cleveland).
The fourth official is Mr. W. Grunnill (East Yorkshire).
