Nottingham Forest manager Steve McClaren must decide whether to make changes or give those players that started the heavy midweek to Burnley a chance to redeem themselves.
After beating Watford 1-0 away last weekend, McClaren made two changes at Turf Moor. Andy Reid and Matt Derbyshire were recalled as Lewis McGugan and Robbie Findley dropped down to the bench.
Forest found themselves 4-0 behind at half-time before eventually going on to lose 5-1.
With Paul Anderson (hamstring), George Boateng (ankle), Garath McCleary, Chris Cohen and Dexter Blackstock (all knee) out injured, McClaren's options are limited should he wish to make changes.
However, McGugan, Findley, Marcus Tudgay, Radoslaw Majewski and Brendan Moloney are available.
Four defeats in the last five Championship matches have left Forest 20th in the table and just one point outside the bottom three.
Birmingham could have defenders Curtis Davies and Stephen Carr back.
Boss Chris Hughton had feared the worst after Davies injured his knee and calf against Barnsley last Saturday but was relieved to learn the problem was not long term.
Davies and captain Carr, who also suffered a minor knee problem against the Tykes, missed the Europa League win away to NK Maribor but are being assessed ahead of the trip to the City Ground.
Midfielder Keith Fahey and striker Nikola Zigic came through the Maribor match with no setbacks and Hughton reported no new issues following the European clash.
