Dunn unlikely to face Blues
Dunn picked up the injury in last week’s 1-0 win over Everton and is not expected to be fit for selection until after the match at St Andrew’s.
The same applies to Vince Grella (calf), but Rovers boss Sam Allardyce hopes to have both players back for next week’s Carling Cup encounter with Norwich.
Rovers (from): Robinson, Salgado, Chimbonda, Jones, Givet, Nelsen, Samba, Olsson, Jacobsen, Emerton, Nzonzi, Andrews, Kalinic, Pedersen, Hoilett, EH Diouf, MB Diouf, Brown.
