Mick McCarthy deserves huge praise for guiding Cardiff up the table in his three months in charge, but the manner of Monday's loss at Hillsborough would have hurt the Yorkshireman.
City quite simply did not turn up and were three goals down inside 23 minutes en route to what McCarthy described as a "humbling experience" for his players.
The five goals conceded against Wednesday was as many as McCarthy's men had let in across their previous 10 league games combined.
That loss came on the back of a 1-0 home reverse at the hands of Nottingham Forest, leaving Cardiff eight points off the playoffs with six games to go.
A top-six finish is not quite mathematically impossible just yet, especially with sixth-placed Reading up next, but the Bluebirds now effectively need to win each remaining game.
That starts with Saturday's visit of Blackburn, who themselves have lost successive games without scoring since the international break.
Tony Mowbray's charges went down 1-0 to Wycombe Wanderers and 2-0 to Bournemouth, making it one win in their last 14 matches.
The pressure is understandably growing on Mowbray, with his side completely collapsing since mid-December time to drop from sixth at one point to their current position of 17th.
Relegation cannot be entirely ruled out yet, sitting potentially just four points above the dotted line if Rotherham United win their games in hand to climb out of the dropzone.
Blackburn tend to do well against Cardiff, though, going four without defeat in this fixture since 2016, including a well-earned point in the reverse meeting six months ago.
McCarthy will surely be tempted to make mass changes to his side on the back of the thrashing to Wednesday, though back-up options are somewhat limited.
As for Blackburn, Joe Rothwell added to Mowbray's list of absentees when limping off in the first half of Monday's defeat to Bournemouth.
Adam Armstrong did return from injury last time out, but he marked his comeback with a penalty miss late on.
Fellow attacker Harvey Elliott is growing more and more important for Rovers, having assisted 10 goals in the Championship this term - only Norwich City's Emiliano Buendia (15) has more.
Cardiff City possible starting lineup:
Phillips; Nelson, Flint, Brown; Sang, Ralls, Vaulks, Ng; Wilson, Moore, Ojo
Blackburn Rovers possible starting lineup:
Kaminski; Nyambe, Lenihan, Harwood-Bellis, Douglas; Holtby, Johnson, Trybull; Elliott, Armstrong, Gallagher
We say: Cardiff City 0-0 Blackburn Rovers
Both sides could really do with a victory this weekend to put a bad run of form behind them.
Cardiff are 12 points better off than Blackburn, but six of the last nine encounters between these sides have finished all square, which we can see being the case again here.
