Lee Clark named the same starting XI for Tuesday's 1-0 win at Bristol City as the one which claimed a 2-2 draw at Leicester last Friday, and the Blues boss has no new injury or suspension concerns.
Midfielder Jonathan Spector again misses out with his troublesome ankle injury and watches from the stands alongside fellow absentees Keith Fahey, Marlon King, Stephen Carr, David Murphy and Will Packwood.
City's midweek triumph took them up to 12th in the table, just one place and one point below opponents Leeds.
Birmingham are currently six points clear of the drop zone with three matches remaining but in what has proved to be one of the tightest relegation battles in recent memory, even ninth-placed Charlton are not yet sure of their Championship status - with eight points separating 15 teams.
