Craig Gardner - the goal hero in Wednesday's Carling Cup semi-final extra-time win over West Ham - is doubtful with an ankle injury along with defender Roger Johnson (calf) and striker Cameron Jerome (hamstring).
McLeish is also considering resting the likes of veteran skipper Stephen Carr and midfielder Barry Ferguson ahead of next week's Barclays Premier League meeting with Manchester City at St Andrew's.
On-loan Tottenham winger David Bentley will be available after being cup-tied against the Hammers while Maik Taylor, Stuart Parnaby, David Murphy, Jordan Mutch, Jean Beausejour, Kevin Phillips and Keith Fahey are also in contention.
