While Blues currently sit six points clear of the bottom three, Rotherham will halve the gap between themselves and their next opponents with victory at the New York Stadium.
With three games having been played in less than a week, Rotherham boss Paul Warne will be relatively content with claiming four points during that period.
Nevertheless, the Millers could ill-afford to lose to Coventry City, and their 1-0 reverse to the Sky Blues has made it increasingly difficult to avoid the drop.
Still possessing two fixtures in hand, Warne will not panic at this stage, but there is now a greater need to get maximum points from Sunday's encounter.
On a positive note, taking advantage of their extra matches will currently take Rotherham into 18th position, a scenario which keeps the pressure on the teams above them.
With all three of Rotherham's goals against Queens Park Rangers coming after the break, they have now failed to score in nine of their last 10 halves of football.
Birmingham's record in the final third is also nothing to brag about with just five goals being scored in as many games since the arrival of Lee Bowyer.
However, the former Charlton Athletic boss has delivered 10 points, a return which has left Blues on the brink of securing their second tier status for another 12 months.
Defeat on Sunday would change the mood at St Andrew's, but Bowyer will feel that his well-rested squad are in the ideal position to outlast their hosts.
Bowyer will be forced into at least one change with Alen Halilovic having been ruled out through injury.
Daniel Barlaser should also feature after remaining as an unused substitute on Thursday night.
Rotherham United possible starting lineup:
Johansson; Ihiekwe, MacDonald, Wood; Harding, Wiles, Barlaser, Wing, Giles; Smith, Ladapo
Birmingham City possible starting lineup:
Etheridge; Dean, Roberts, Pedersen; Colin, Sunjic, Gardner, Friend; Sanchez, McGree; Jutkiewicz
We say: Rotherham United 1-1 Birmingham City
Aware of the consequences of defeat, Rotherham are unlikely to come out firing on all cylinders on Sunday. Nevertheless, the Blues will be more than happy with a share of the spoils, leading us to predict a low-scoring draw.
