Paul Warne has named his side to face Floridsdorfer at FAC-Platz this evening, kick off 6pm (GMT) and 7pm (local time).
The match, with updates provided on the Millers' official twitter account, will see the Warne's side play their first friendly of their pre-season tour of Austria.
New signing Kieffer Moore will don a Rotherham shirt for the first time, whilst Jon Taylor and Jerry Yates are both returning to action.
Warne will play his first 11 for 60 minutes before switching formation and personnel for the final 30 minutes.
Here he explains how his side will set up:
"In the first-half I am going to play 4-4-1-1. Dom Ball is going to play centre-half with Richard Wood tonight because Semi Ajayi still has a sore back. They haven't played together yet, and Woody hasn't played with Purrington who will play at left-back, so it was important to give them game time.
"On the other side Ball and Fisher haven't played together so this is a chance for them to link up with each other.
"In midfield I am going with Darren Potter and Will Vaulks, so they can compete for a shirt because they haven't played together yet. We'll go with Newell on the left and Forde on the right, they have done really well so far.
"In the hole I am going with David Ball just behind Kieffer Moore who will play for the first time.
"I am playing that team for 60 minutes, and then the lads will rotate again for the game on Saturday.
"For the last 30 minutes we are trying a 3-4-1-2 formation. Richard O'Donnell will play in goal. The three at the back will be Mattock, Ihiekwe and Ball. Dom is going to play 90 minutes which will do him good.
"Bray will play on the left. He has been a bit ill, but he is getting better and we feel he can handle 30 minutes. Frecks will then partner Potter. Potter will play the 90. He is the sitting midfielder so there should be no issues. On the right I have Jon Taylor. He has just joined the training group again.
"Jerry Yates is also back in training and we'll have him just behind the front two of Jonson Clarke-Harris and Jamie Proctor.
"Semi Ajayi has a sore back, but he is a lot better today than he was yesterday. Ryan Williams is suffering with a little bit of sickness. Alex Bray had it the day before, and it has passed on to Ryan. I don't want that to go through the group obviously, so we are keeping him out tonight.
"The lads have trained this morning twice, so they won't be as fresh as they were for the Parkgate match, but they have worked really hard and they can all play even with a bit of fatigue."
Team in full (first 60): Price; Fisher, Ball, Wood, Purrington; Forde, Potter, Vaulks, Newell; Ball, Moore.
Last 30: O'Donnell; Ball, Ihiekwe, Mattock; Taylor, Potter, Frecklington, Bray; Yates; Proctor, Clarke-Harris.
