Leicester caretaker managers Jon Rudkin and Mike Stowell may still be without Darius Vassell and Lloyd Dyer for the visit of Leeds.
The pair picked up injuries in the 3-2 defeat at West Ham and subsequently missed the Foxes' 3-1 win against Burnley.
Both are considered doubtful for the match, meaning Paul Gallagher and Steve Howard are expected to retain their places in the starting XI.
Jermaine Beckford will also hope for a place in Rudkin and Stowell's line-up against his former employers.
Leicester will be aiming for their first back-to-back wins of the season against Leeds, as the club look to put their managerial search to one side for the time being.
Skipper Matt Mills told the club website: "It's been mentioned that we've not won two on the bounce. That's something that's ringing in our ears so we want to put it right."
Leeds' new loan signing Alex McCarthy is expected to go straight into the starting line-up in Sunday's clash at Leicester.
Manager Simon Grayson has drafted in cover for Andy Lonergan, sidelined until next month due to a broken finger, and England Under-21s international McCarthy is likely to make his debut.
But Leeds will be without suspended defender Tom Lees, who was shown a straight red card for deliberate handball in the midweek defeat to Blackpool. The 20-year-old sits out an automatic one-game ban.
Patrick Kisnorbo returned to the starting line-up in central defence on Wednesday night in place of Darren O'Dea, who had been suffering from blurred vision and dizziness following a collision during last Sunday's home draw with Cardiff.
Andy O'Brien, Alex Bruce and Leigh Bromby will all come into contention in Lees' absence.
Grayson has no new major injury problems, but could be tempted to make other changes after Leeds lost 5-0 to his former club Blackpool in midweek.
