McLeish is to keep faith with the 18 players on duty in last Saturday's FA Cup fifth-round win over Derby at Pride Park.
The former Scotland boss has more midfield options after the arrival of Craig Gardner and Michel during the January transfer window.
He left out James McFadden and Sebastian Larsson for the previous league game at West Ham 10 days ago and brought in Gardner and Keith Fahey as the wide players.
Birmingham (from): Hart, Carr, Johnson, Dann, Ridgewell, Larsson, Bowyer, Ferguson, McFadden, Jerome, Benitez, Taylor, Phillips, Michel, Fahey, Parnaby, Vignal, Gardner.
