Doncaster ended a nine-match winless streak with a surprise 3-0 win over Wigan Athletic on January 18 and have since drawn with Blackpool and beaten fellow strugglers Charlton Athletic, also by three goals to nil.
That string of results has seen them burst out of the bottom three, and they could move as high as 17th with another victory on Saturday.
They are now four points clear of the relegation zone and have kept clean sheets in their last three home league games having not kept one at the Keepmoat since October before that.
Manager Paul Dickov will be stressing to his side that they are by no means safe yet, but with returning striker Billy Sharp already back amongst the goals, the hosts will be confident going into Saturday's match.
Middlesbrough will certainly ask questions of Doncaster's renewed confidence as they still have hopes of challenging for the playoffs this season.
They currently sit 10th in the Championship table and are now seven points off the top six after a period of inconsistency that has seen them lose two, win two and draw two of their last six games in all competitions.
Looking just at league form, however, only runaway leaders Leicester City have beaten Middlesbrough in the Championship in their last eight outings.
Worryingly for Aitor Karanka, the goals seem to have dried up a little for his side, with just one coming in their last three matches.
However, on a more positive note, the visitors' away form has improved recently, with a 2-0 defeat to Leicester being their only loss on their travels in five games having gone nine games without an away win before that.
A win by a big enough margin, coupled with other results going their way, could see Middlesbrough rise as high as seventh in the table and would give their playoff hopes a massive boost.
