Birmingham welcome back captain Stephen Carr for the game.
The veteran right-back missed the club’s Europa League and Championship victories against NK Maribor and Nottingham Forest prior to the international break due to a knee injury.
Jonathan Spector is also expected to be okay having been forced off early on against Forest with an ankle injury.
However, centre-back Curtis Davies, who has also missed the last two games with knee problems, is not ready to return for another couple of weeks.
Promising young midfielder Jordon Mutch is targeting a mid-November return from the broken ankle he sustained in August.
Meanwhile, eight-goal leading scorer Chris Wood will be pushing to regain his starting berth as he kicks off the latest spell of his youth loan from West Brom having seen his previous deal expire following his brace against Forest.
Leicester have several key players nearing a return from injury as Sven-Goran Eriksson’s in-form side prepare to face their Midlands rivals.
Richie Wellens and Michael Johnson resumed full training this week, while Eriksson is hopeful that fellow midfielder Andy King and striker Jermaine Beckford will be available on Sunday.
Wellens (groin), Johnson (shoulder) and Beckford (groin) all missed the 4-0 home victory over Derby prior to the international break and King withdrew from the Wales squad last week after sustaining a back injury against the Rams.
However, Paul Gallagher is unlikely to feature this weekend despite the forward making good progress after more than a month out with an ankle injury.
Defenders Sean St Ledger (Republic of Ireland) and John Pantsil (Ghana) and midfielders Gelson Fernandes (Switzerland) and Yuki Abe (Japan) are expected to return from international duty unscathed.
Leicester go into the game on a seven-match unbeaten league run and having kept four consecutive clean sheets.
