It seems some fans already want the Forest boss's head. Many, however, have leapt to his defence.
"We were reasonably pleased in the first half to come in ahead. We felt we could get on top of them in the second half; we felt we could get a second goal.
"But we did not take the game by the scruff of the neck and the more Blackburn got on top of us, the more we did not show the leadership required to stem the flow.
"It was a disappointing afternoon and I am not going to gloss over that."
Pearce's side are now on a terrible run of form, although this was only their first home defeat of the season. Forest have dropped from first to seventh and many critics argue that their performance levels have gone from bad - even when they were winning - to worse after this Blackburn loss.
But it seems a sizeable portion of Nottingham Forest fans are having none of it. Any calls for Pearce's head are being dismissed and the team, despite a disappointing defeat, has plenty of time to gel. Here are the best fan reactions on Twitter...

Was disappointed in the result but you know what we have a great chairman, great manager & stability at the club what more do we want #NFFC— Marc 'Smurf' Twaite (@MarcTwaite) October 26, 2014
Yes I am too backing Pearce but he has to be accountable for the losses and so do the players #nffc— Luke musto (@lukeymustard) October 26, 2014
Dont see why #nffc fans are moaning ,were only 14 games in alot of time to change— Dunni (@Forest_Lad_1994) October 26, 2014
Can't sack Pearce after 3 months, but we've played badly all season, and it's getting worse, not better. Stop Antonio and you stop #nffc— My Desire Is Always (@MyDesireIs_) October 26, 2014
No one was more gutted than me after yesterday's result but the minority of idiots calling for SP to go need to support someone else #nffc— Andrew McCourt (@Nottingham67) October 26, 2014
