All three players missed the 1-1 draw with Championship leaders Cardiff in midweek.
De Laet (ankle) joined the already sidelined Konchesky (hamstring) and James (knee) in the treatment room after he was carried off on a stretcher towards the end of Leicester's 1-0 home defeat to Sheffield Wednesday last Saturday.
The fit-again Sean St Ledger played his first 90 in five months at right-back against Cardiff while striker Jeff Schlupp again deputised for Konchesky at left-back in the Welsh capital.
Manager Nigel Pearson has options should he wish to make any changes to his starting line-up with defender Zak Whitbread, wingers Ben Marshall and Anthony Knockaert and strikers Jamie Vardy, Martyn Waghorn and Harry Kane all pushing for recalls.
