Leicester manager Nigel Pearson expects to have a fully-fit squad for the visit of Birmingham.
It means the Foxes boss has options should he wish to alter the team that started last weekend's 1-1 draw with fellow play-off chasers Brighton.
Defender Ritchie De Laet and strikers Chris Wood and Harry Kane were introduced from the bench at the Amex Stadium.
Central midfielder Richie Wellens and wingers Lloyd Dyer and Anthony Knockaert were unused substitutes on the south coast.
All six players will be pushing for a recall on Friday night as Leicester look to end a eight-game winless run with a victory that would, ahead of Saturday's fixtures, see them move above Brighton and into the final play-off spot.
Chris Burke and Shane Ferguson return to contention for Birmingham.
Scotland international winger Burke has missed the past three matches due to an ankle injury but has now returned to training ahead of the the clash at the King Power Stadium.
Fellow wide man Ferguson, on loan from Newcastle, played no part in last Saturday's 1-1 draw against Millwall due to illness but is also back in the fold.
However, midfielder Jonathan Spector misses out with a recurrence of his ankle injury having been forced off at half-time versus the Lions.
Keith Fahey is set to miss the remainder of the season with his troublesome hip injury and is sidelined along with fellow long-term absentees Marlon King, Stephen Carr, David Murphy and Will Packwood.
