Birmingham will be without Tom Adeyemi and Peter Lovenkrands for their delayed FA Cup third-round tie at home to Bristol Rovers.
Midfielder Adeyemi continues to struggle with a back injury while striker Lovenkrands is missing with a groin problem as Blues attempt to set up a fourth-round showdown at home to Swansea.
Young defender Amari'i Bell is cup-tied following his involvement in the competition earlier this season on loan at Nuneaton.
Kyle Bartley (hamstring), David Murphy, Matt Green, Neal Eardley (all knee), Jonathan Spector (thigh) and Akwasi Asante (hamstring) all remain sidelined, while midfielder Darren Ambrose is poised to complete a loan move to Greek Super League side Apollon Smyrni until the end of the season.
Bristol Rovers boss John Ward has no fresh injury worries.
The Pirates ran out 2-1 winners against Exeter on Saturday and Ward confirmed his players are raring and ready to travel to St Andrew's.
"I don't think anybody will be missing on Tuesday, they are ready for their treat," he said. "It is a treat to go to Birmingham and I'm sure that will lift people."
Danny Woodards made his long-awaited return from injury as a second-half substitute against his former club on Saturday and Ward is likely to include the ex-MK Dons full-back in the squad again.
