Malky Mackay is likely to make wholesale changes to the Cardiff side who beat Leicester on penalties in the Carling Cup, when the same opposition return for their npower Championship clash on Sunday.
Mackay made seven alterations to his starting XI for the midweek tie, with striker Kenny Miller and defender Kevin McNaughton not even figuring among the substitutes for the Bluebirds.
Both are expected to return to the starting line-up for the second meeting with the Foxes in five days, but Mackay is not without injury problems.
Defender Ben Turner is unlikely to be handed his debut after picking up an impact injury during the week, while full-back Andrew Taylor came off against the Foxes with a slight hamstring scare.
Meanwhile, midfielder Stephen McPhail is battling a groin strain but should be fit for the fixture.
Leicester boss Sven-Goran Eriksson is also expected to return to his strongest XI as he takes his side back to the Welsh capital.
The City manager swapped 10 players for the third-round tie in south Wales on Wednesday night, which finished 2-2 after extra-time.
Captain Matt Mills was the only survivor from the league victory over Brighton last Saturday. The centre-half was substituted at half-time, but Eriksson insisted it was just a precaution.
"He has had some groin problems but they are not serious and he will be ready for Sunday," said the Swede.
Kasper Schmeichel, Lee Peltier, Sol Bamba, Paul Konchesky, Yuki Abe, Gelson Fernandes, Richie Wellens, Andy King, Darius Vassell and Jermaine Beckford dropped out of the team in midweek but the majority, if not all, are expected to be recalled.
