The two sides, who were both relegated from the Premier League the season before last, lie on 42 points and are just six points clear of the drop zone.
When the two sides last met in November, it was a 1-1 draw and a stalemate again seems likely.

Birmingham: Butland; Caddis, Davies, Caldwell, Hancox; Burke, Reilly, Elliott, Spector; Lovenkrands, Zigic
