Leicester have been monitoring Curtis Davies and Miguel Vitor ahead of the visit of Leeds.
Both players are nursing injuries following the defeat in the snow at Ipswich. Davies was forced off midway through the second half at Portman Road with a tight hamstring, while fellow defender Vitor complained of a groin problem after the game.
Jack Hobbs, Davies` replacement in Suffolk, and Michael Morrison are on standby.
Roman Bednar missed out last weekend with a knock and the striker is likely to come straight back into the team if he has recovered.
Midfielder Matt Oakley and striker Steve Howard could also be in line for recalls should boss Sven-Goran Eriksson wish to make further changes.
