Goals from Michael Chopra and Aaron Ramsey gave Cardiff a 2-0 victory but Eriksson said Leicester would come out fighting against Coventry at the Walkers Stadium on Saturday.
"We will bounce back, I am sure of that," said the Swede.
"We will be disappointed but, when we get back into training on Thursday, we will pull ourselves together and go on fighting.
"It is important that we bounce back against Coventry on Saturday and then QPR away. The next games for us are extremely important because the teams above us can afford to lose a few games and still be in a good position.
"We can't afford to lose many points in the last 13 games if we want to have a chance of getting promoted."
