Rovers suffered last-gasp heartache for the second week running, as West Brom left it late to secure a 2-1 win at Ewood Park.
With just a minute of normal time remaining, Peter Odemwingie scored a spectacular winner to condemn Rovers to a second successive dramatic defeat.
Scott Dann thought he'd rescued a point for Rovers&nbsp;when&nbsp;he got on the end of Chris Samba's knock down to score his first goal for the club 18 minuites from time.
After a goalless first-half,&nbsp;a James Morrison wonder-strike had given the Baggies the lead.
Before the game, Rovers made two changes to the side that lost at Sunderland last weekend.
Steven Nzonzi was&nbsp;back after a ban, while&nbsp;Ruben Rochina returned&nbsp;from injury. Gael Givet (heart) and Michel Salgado (ribs)&nbsp;both dropped out, whilst Martin Olsson and Junior Hoilett failed to recover from&nbsp;hamstring strains.
Morten Gamst Pedersen started the game&nbsp;at left-back.
The visitors registered the first shot of the game on five minutes, Morrison finding Odemwingie in space on the left, but the Nigerian blazed high and wide.
Odemwingie threatened again 10 minutes later, Chris Brunt with the ball in from the left, but the striker flashed a free header just wide of the far post.
Rovers' first real attack arrived on 17 minutes, Yakubu playing the ball out wide to Jason Lowe, who cut inside and his attempted shot fell kindly for the Yak, who just couldn't connect on the slide.
Odemwingie was seeing plenty of the ball in the early exchanges and a speculative shot on 20 minutes was spilled round the post by Paul Robinson.
As the half wore on, Yakubu was becoming increasingly frustrated by a series of marginal offside decisions. At the other end, Robinson pulled off a superb reaction save to deny Shane Long from close range, but the Irishman had also strayed offside.
On 38 minutes, Paul Scharner was booked for a synical foul on Mauro Formica and Pedersen's free-kick had to be tipped over the bar.
Four minutes before the break, Yakubu played in David Dunn, who broke into the box, but was denied by a robust goal-saving challenge by old pal Steven Reid.
Just like the first half, Albion registered the first attempt of the second half five minutes after the interval. The ball was worked wide to Morrison, who pulled it back to Scharner, who dragged his shot agonisingly wide of the far post.
Less than two minutes later and the visitors took the lead. Brunt's inswinging corner from the right was cleared by Nzonzi, but Morrison struck an unstoppasble first-time volley past Robinson from 20 yards.
Formica tried his luck with a long-range effort shortly after, but it swerved just wide.
Rovers made a double change just past the houyr mark, with former Baggies striker Jason Roberts replacing Simon Vukcevic and Grant Hanley coming on for Dunn, with Lowe moving into midfield.
The attacking switch paid dividends as Rovers equalised 10 minutes later. A long Robinson free-kick from inside his own half was nodded down by Samba and defensive partner Dann stole in unmarked to fire home at the far post.
Both sides went for the winner late on, with Morrison blazing over the bar, before stinging the gloves of Robinson.
At the other end, Nzonzi and Yakubu both had shots comfortably saved by Ben Foster.
There was still time for Rovers to be cruelly robbed again at the death, as in the 89th minute, Odemwingie cut inside Pedersen and David Goodwillie from the right, before firing a sweet left-foot shot past Robinson from the edge of the area.
Rovers now turn their attentions to Bolton Wanderers on Tuesday night for another crucial Ewood encounter.
