The trip to south Wales has the Millers aiming to end a five-game losing streak on the road.
Here's an in-depth preview of the game at the Cardiff City Stadium.
Team news
Rotherham will add new signing Luciano Becchio to the squad, but the striker will be on the bench.Fellow new signing Chris Burke will also travel with the squad and looks set to make his debut on the right of midfield, with Grant Ward moving to a more central role.
Skipper Lee Frecklington is back in training after a hamstring injury but won't feature, though Farrend Rawson is fit again after a hamstring problem of his own.
Lewis Buxton is also added to the squad after his ending his contract dispute.
What the manager says
On the Millers' poor away form
"We have got to get the level of performance right. We have been playing a lot better and I know that if we get the level of performance right the chances are we will start picking up the odd result. We have got to offer a real threat away from home."On Cardiff
"They are a good side. They are always round about, they will be hoping to sneak into the play-offs this year. Russell Slade is an experienced manager who knows this division well. They will be a tough nut to crack. They have basically got Premier League players."The opposition
Cardiff are under a Football
League transfer embargo, but they have still added to their squad this week
with the loan signing of Lex Immers.
The 29-year-old forward has
joined from Feyenoord until the end of the season and is set to make his debut
against the Millers.
Defender Sean Morrison
remains sidelined with a knee injury, while striker Idriss Saadi is still out
after tearing his hamstring on debut in November.
The Bluebirds are five points
adrift of the play-offs and won their last outing 3-1 at Wolves. That win
alleviated the pressure on boss Russell Slade, who was reported to be facing
the sack after a disappointing FA Cup exit to Shrewsbury.
Things to look out for
Ending away-day blues
Rotherham have a severe case of travel sickness, having lost eight of their last nine matches on the road. If the Millers are going to stay up this season they have to be able to pick up some results away from home and boss Redfearn knows it. He could be tempted to switch to a 4-4-2 against the Bluebirds, something the Millers have not deployed on the road since their win at Leeds in November.
Alex Revell reunion
The Millers are likely to come face-to-face with Alex Revell on Saturday, with rumours linking him to a return to South Yorkshire this month. The arrival of Immers from Feyenoord could tempt the Bluebirds to let him out, but it is likely that Revell will be involved in the matchday squad on Saturday. If he gets on, he could be performing an audition.
