Blackburn's 1-1 draw with Crystal Palace last weekend leaves them 17th in the Championship table, level on points with Barnsley, who occupy the final relegation spot. However, Rovers have a goal difference which is seven better than Barnsley's.
Birmingham have no fresh injury concerns ahead of the match and could field the same side which started the defeat at Portman Road.
Possible starting lineups
Birmingham: Butland; Caddis, Davies, Robinson, Hancox; Redmond, Elliott, Mullins, Ferguson, Morrison; Zigic
Blackburn: Sandomierski; Dann, Kane, Hanley, Williamson; Morris, Jones, Dunn; Nuno Gomes, Goodwillie, Rhodes
