The Bluebirds have gone six matches without defeat and are in possession of the final playoff spot, eight points better off than out-of-form Rovers.
Blackburn won their first game back after the Championship season resumed last month - a 3-1 home victory over Bristol City - to close to within one point of the playoffs.
Since then, however, they have lost to Wigan Athletic, Barnsley and Leeds United, seeing them drop down to 11th place in the division.
That is the position Cardiff occupied on their return to action, but they have been in superb form over the past few weeks and are well on course for a top-six finish.
Going further back, it is four wins and two draws for the Welsh outfit in their last six matches, not only seeing them climb into the playoffs but also build up a three-point buffer on the chasing pack.
Neil Harris's men now face three successive games against sides chasing them down, though, starting with this visit of Blackburn.
Anything other than three points for Rovers will end their slim hopes of promotion, and recent history suggests that they will be lucky to come away from South Wales with a win.
The Blue and Whites have failed to win any of their last 10 encounters with Cardiff since a 3-2 FA Cup win in January 2005.
Blackburn are also winless in four matches on their travels, losing the last three of those without scoring a single goal.
Cardiff have not exactly been in rampant form on home soil, though, having picked up maximum points only once in six league matches at the Cardiff City Stadium.
Cardiff City's Championship form: DWWWDW
Blackburn Rovers' Championship form: DLWLLL
Cardiff's large squad has come to good use since the restart, with Harris tending to make the right substitutions at the right time.
That was the case again on Saturday as Ward and Tomlin linked up for the winner at Ashton Gate, and the pair should be fit enough to start this clash against Blackburn.
As for Blackburn, Darragh Lenihan was back involved last time out after missing the trip to Barnsley due to the birth of his son.
Elsewhere, Adam Armstrong scored an impressive free kick against league leaders Leeds and will be looking to add to his tally of 13 goals this term.
Cardiff City possible starting lineup:
Smithies; Sanderson, Morrison, Nelson, Bennett; Ralls, Bacuna; Mendez-Laing, Tomlin, Murphy; Ward
Blackburn Rovers possible starting lineup:
Walton; Nyambe, Lenihan, Adarabioyo, Bennett; Downing, Johnson, Rothwell; Samuel, Gallagher, Armstrong
We say: Cardiff City 1-0 Blackburn Rovers
Cardiff have momentum on their side heading into the final five games of the Championship season. Blackburn, by comparison, have run out of steam and we are expecting their poor away streak to continue on Tuesday.
