Rovers’ play-off hopes are now hanging by the most slender of threads after falling to defeat against top six rivals Bradford.
Second half goals from Gary Mackenzie, Billy Clarke and Tony McMahon saw the Bantams take all three points from the Keepmoat.
It was a game Rovers so desperately needed to win after Good Friday’s afternoon results left them seven points off sixth spot in League One.
And the hammerblow of a defeat sees them remains that imposing margin away from the play-off places with six teams ahead of them and only a solitary game in hand.
The match saw the return to the Rovers starting XI of James Coppinger after his ankle injury.
But he could not provide the spark needed to ignite the side.
It proved a particularly competitive first half with both sides enjoying strong spells of possession.
Jonson Clarke-Harris was inches away from giving Rovers the lead inside 30 seconds of the derby clash with Bradford.
The Rotherham United loanee surged to meet Harry Forrester’s low cross but turned his effort agonisingly wide.
Clarke-Harris was involved in another big moment on 18 minutes when he appeared to be pushed to the ground inside the box by Stephen Darby but the referee was unmoved.
Both sides enjoyed good spells of pressure during a competitive first half.
Clarke-Harris twice headed wide from Forrester deliveries as Rovers pushed around the half hour mark.
Mark Yeates forced Stephen Bywater into a fine save at his near post as the visitors pushed.
Curtis Main rattled the bar in the last few minutes of the first half.
Big defender Mackenzie poked home after a goalmouth scramble from Filipe Morais’ cross to give the Bantams the advantage on 55 minutes.
Rovers almost levelled immediately after Mackenzie’s opener when Dean Furman drew a stunning save from Ben Williams.
But then Clarke struck with the hammerblow. James Hanson surged through and laid off to Clarke who slammed home past Stephen Bywater to put Bradford in full command with 26 minutes left.
Rovers looked dead and buried after the disappointment of conceding a second and even a debut for promising youngster Liam Mandeville could not lift them.
And Bradford stuck in the knife in added time. Substitute McMahon pounced as Reece Wabara slipped and galloped through before slotting past Bywater.
