Right-back Ritchie De Laet overcame a back problem to play against Burnley on Saturday, while centre-half Zak Whitbread and striker Jamie Vardy (heel) missed the trip to Turf Moor through injury.
On-loan Manchester United defender Michael Keane returned to the squad against the Clarets after several weeks out with a hamstring injury and was an unused substitute.
Pearson may opt to rest De Laet while it remains to be seen if Whitbread or Vardy are ready to come back, or whether Keane is ready to start a npower Championship fixture.
The Foxes boss has the likes of midfielders Andy King and Paul Gallagher and strikers Martyn Waghorn, Jeff Schlupp, who has also proved this season that he can play as a makeshift left-back, and Marko Futacs available to make changes.
He said: "There will be a few players who will be fatigued but we have options to freshen it up. We have to dust them down and see how they are and go from there.
"We have competition for places and we have players who could come in."
