McCarthy has guided the Blues to seven wins from 12 games since taking charge, which has moved them eight points clear of the relegation places.
With no new injury or suspension concerns, McCarthy is likely to keep faith will all of his starting XI.
The ex-Wolves manager, who led his team to a 2-0 win at his former club on Saturday, has a number of options should he choose to rotate his squad for their fourth game in 11 days.
Experienced pair Nigel Reo-Coker and Michael Chopra made substitute appearances at Molineux and will be pressing for starts.
Jay Emmanuel-Thomas and Jason Scotland offer further attacking options while Danny Higginbotham, who has not featured for the Tractor Boys since November, is also waiting in the wings.
