Danny is only standing in his second full season on the referees panel, and has taken charge of the Millers on one previous occasion, a 2-0 defeat at Cheltenham last season in which five players were booked.
This was one of 26 games last season, in which he produced 92 yellows and four reds.
Worryingly this season though, he's dished out the red card seven times in just 16 games, with 43 players on the receiving end of a yellow. Anything has to be better than Nigel Miller on Saturday though, unless your name's Trevor Kettle.
His assistants tomorrow will be C. Reeves and J. Waugh (Yorkshire)
The fourth official is Mr P. Graham (Greater Manchester)
