Boss Gary Bowyer bemoaned defensive lapses as Rovers tasted defeat on the road with a 3-1 loss to Wolverhampton Wanderers.
First half goals from Nouha Dicko and Bakary Sako saw Rovers trail at the break, before Jordan Rhodes pulled a goal back from the penalty spot just before the hour.
With Rovers pushing for an equaliser they were caught at the back, Sako applying the finishing touch after Dicko's good work.
"We can't keep coming away from home and conceding soft goals," said the Rovers boss. "That is the disappointing thing.
"There's no point saying we had the lion-share of possession, we've played well and we've been the more dominant team and be talking about losing three points.
"The very first cross that they put into our box they score from. We should have defended it better, there is no doubt about that.
"Then their goalie has made a fantastic save from Ben Marshall and another couple of saves.
"Then there's a free-kick not given right in front of the bench when Craig Conway gets fouled. They go down the other end and he gives a free kick to them and they score from it. So to be 2-0 down at half-time I thought it was harsh.
"In the second half we had the majority of the play and once we get it to 2-1 Wolves are the team that are playing counter-attack football when we are the away team.
"We've come and dominated possession but unfortunately we've conceded soft goals and have not been clinical enough in the final third and I think that sums the game up."
"Because of the break this defeat is now going to last two weeks and that is really disappointing."
