Jeremie Bela has added to Birmingham’s injury woes ahead of the clash with Midlands rivals West Brom.
The winger had to be withdrawn early in the second half of the home defeat to QPR on Wednesday night due to a groin problem.
Blues head coach Pep Clotet is already without Dan Crowley (hamstring), Jake Clarke-Salter (shoulder), Marc Roberts (ankle), Maikel Kieftenbeld (knee) and David Stockdale (hand).
Some good news for Clotet is Fran Villalba is available once again after recovering from a hamstring issue, while Gary Gardner is slowly returning to contention following a knee injury.
West Brom boss Slaven Bilic could again make changes to his starting line up.
Bilic swapped four players, one enforced due to an injury to Kieran Gibbs, as his team drew at Wigan in midweek so Hal Robson-Kanu, Matheus Pereira and Grady Diangana could be recalled at St Andrew’s.
Gibbs (hamstring) remains a doubt so Conor Townsend may continue at left-back in his absence.
Kyle Bartley (head) had been a doubt for the game against Wigan but he was able to feature and is back in contention.
