The Foxes face a hectic programme over the next month with a midweek game every week until after the home clash with Sheffield Wednesday on Saturday March 9, and further progress in the FA Cup could cause even more fixture congestion.
Pearson's players potentially have nine games in the next five weeks, starting with Saturday's npower Championship trip to Peterborough.
"We have had to reschedule one or two games, but I would rather be in the competition (FA Cup) than not," said Pearson, whose side host Huddersfield in a fourth-round replay on Tuesday for the right to play Wigan at home on February 17.
"It would have been nice to have got a positive result in the first game but we will deal with it. We have an important game between now and then so I won't worry about that.
"We have worked hard on limiting the number of training injuries we have and we have been successful in doing that.
"But, throughout the course of a season, you will pick up some injuries and I think it is important now that we try to manage the squad as best as we can to try and keep as many players available as possible."
