Liam Noble bagged a brace as Carlisle claimed a shock 2-0 win at leaders Doncaster.
Noble's first goal came totally against the run of play after Rovers had forced the pace in the first half hour without really looking like scoring.
Kyle Bennett hit a fierce volley just wide in the 15th minute and Andy Griffin had a scorching 25-yard strike parried by Mark Gillespie 10 minutes later.
Carlisle had not posed a threat but they went ahead in the 33rd minute when a 25-yard free-kick from Noble took a wicked deflection off the defensive wall and looped over goalkeeper Gary Woods into the net.
Rovers came out for the second half with a renewed sense of urgency and determination, with Bennett hitting an angled shot over the crossbar in the 53rd minute.
Chris Brown had a powerful header brilliantly tipped onto the bar by Gillespie before John Lundstram saw a low 20-yard effort saved a minute later.
Brown was out of luck again when he fired against the woodwork in the 67th minute before Carlisle reasserted themselves in the closing stages.
James Berrett had a shot cleared off the line by Jamie McCombe and Noble clinched the points four minutes later when he lashed home a terrific 20-yard shot following a quick-fire break-away.
