Rovers' winless run at the Reebok shows no signs of abating after a disappointing 4-0 loss to Bolton Wanderers.
An injury-ravaged Rovers were no match for a resurgent Trotters side who made it four wins in succession at the Reebok over their Lancashire opponents.
First half goals from Medo Kamara and Joe Mason were added to at the start and end of the second half.
Both were from distance, Jay Spearing's effort was judged to have crossed the line after the ball had bounced down off the crossbar, before substitute Andre Moritz struck with almost the last kick of the game to condem Rovers to defeat.
Chances for Rovers were few and far between, the best both coming for striker and captain for the day Jordan Rhodes, but neither troubled the Bolton goal.
Rovers need to put this behind them, and quickly as Burnley are the opponents next Sunday at Ewood Park.
Ahead of the game Gary Bowyer made two changes from the side that defeated Reading on their travels last time out.
With Grant Hanley and Tom Cairney sidelined with calf and ankle injuries respectively it meant returns to the starting eleven for Chris Taylor and Markus Olsson.
The substitutes bench also saw first appearances for Under-21 regulars Darragh Lenihan and Dean Rittenberg after the pair were awarded squad numbers earlier in the week.
The early momentum was with the home side as they took the game to Rovers from the off.
Tim Ream headed over, whilst Neil Danns' deflected shot needed Paul Robinson to re-adjust to claw the ball away as the visitors struggled to cope with the intensity from the opposition.
The Trotters continued to force the play with Rovers grateful for a sensational ninth minute clearance. Mark Davies had beaten Adam Henley on the left to cut inside and shoot, his effort flashed past Paul Robinson but Matt Kilgallon sensationally cleared the ball away on his own line.
That woke Rovers up with Markus Olsson seeing a shot on the volley tipped away by Adam Bogdan before the Hungarian was called upon once more to deny Jordan Rhodes. The striker broke clear after Jason Lowe's clearance deflected kindly but the Bolton man saved well.
Rudy Gestede was inches away from connecting with a Craig Conway cross, whilst Olsson flashed a right-footed shot well wide in what was turning into an end-to-end encounter.
But just past the midway point of the half it was Bolton who finally got the goal their play deserved. Neil Danns found space just inside the box and he picked out fellow midfielder Medo Kamara who headed back across goal and into the bottom corner of the net.
Aside from a Marcus Olsson pile-driver that skimmed the roof of the net, play was very much with the home side as they continued to press Rovers back.
Former Rover Danns was next to test Paul Robinson, his vicious effort palmed away by Robinson.
Then Joe Mason should have doubled Bolton's lead on 42 minutes when he was played through on goal but Robinson saved well and the on-loan striker poked the rebound wide.
However he wouldn't be so wasteful in added time as he reacted quickest to a blocked shot from Danns to steer the ball into the corner of the net to complete a miserable first half for Rovers.
That poor showing prompted a double change at the break as Corry Evans made a welcome return to first team football. He and Luke Varney on with Chris Taylor and Lee Williamson making way.
Unfortunately for the Irishman his first action was to commit a foul on Neil Danns right on the edge of the box, and although Evans blocked the resulting Jay Spearing free-kick, as the ball was played back into the centre the former Liverpool man struck a sweet shot that flew over Robinson and in off the underside of the bar.
Play continued initially but the linesman on the far side had indicated that the ball had crossed the line and the goal was awarded.
Bolton continued to look the more likely of the two sides to add to the goal tally as Zat Knight and Lukas Jutkiewicz both went close, but Jordan Rhodes should have reduced the scoreline with a header but he nodded Markus Olsson's cross inches wide of goal.
Defender Alex Baptiste was the next Trotters player to try his luck with a 70th minute shot from the corner of the area, his effort fizzing narrowly over the bar.
With 18 minutes to go Rovers were dealt another injury blow as Matt Kilgallon couldn't continue, Todd Kane coming on as his replacement as Rovers were forced to reshuffle once more.
Joe Mason struck the outside of the post before salt was rubbed well and truly into the wounds when a fourth goal was scored in added time. Substitute Andre Moritz capitalising on a poor ball from Evans to beat Robinson from 25-yards.
Rovers need to bounce back after this result, there's the little matter of an east Lancashire derby at Ewood Park next Sunday.
