Birmingham will be without Jake Clarke-Salter and Dan Crowley when they face QPR in a Sky Bet Championship clash at St Andrew’s on Wednesday night.
On-loan Chelsea defender Clarke-Salter is out for three weeks with a shoulder injury sustained in the 3-2 win at Reading on Saturday, while midfielder Crowley picked up a hamstring injury in that game and is sidelined for two weeks.
Manager Pep Clotet at least has midfielders Fran Villalba and Gary Gardner available again. Villalba missed the game with the Royals with a slight hamstring strain, while Gardner has not played since mid-October due to a knee problem
Clotet, though, remains without a number of other players, including Marc Roberts (ankle), Maikel Kieftenbeld (knee) and David Stockdale (hand).
With no fresh injury concerns, QPR boss Mark Warburton is likely to name an unchanged starting line-up.
Rangers ended a seven-match winless streak with a 2-0 victory at home to Preston on Saturday, in which 21-year-old Eberechi Eze scored a brace to take his tally to nine for the season.
Yoann Barbet has a chance of being involved as he closes in on a return after a seven-week absence with a hamstring problem.
Goalkeeper Liam Kelly remains sidelined with a torn thigh muscle, while midfielder Charlie Owens is out with a knee injury.
