The visitors failed to make their numerical advantage count for 85 minutes following Wes Morgan's dismissal in a surprisingly even contest until Alan Dunne popped up to coolly slot home Richard Chaplow's cutback for his first goal in three years.
"I could bemoan a number of things but I think it's pretty unfortunate," Pearson said.
"The players have worked very hard to get something out of the game and to concede a goal so late is, I think, quite cruel. I don't think the players deserve that.
"The players have shown a lot of desire to play in a positive fashion despite going down to 10 men. It's not going for us at the moment but we've got to keep working hard.
"We're not scoring enough goals. We have seven games left and we're losing games by the odd goal. It doesn't mean defeats are any easier to deal with.
"You've got to be careful not to pigeon-hole this performance along with some of our other recent performances. I think we've created some good situations playing with 10 men and still looked pretty dangerous."
