Cardiff City failed to win at home for the first time in six matches after a goalless draw against struggling Rotherham United.
Federico Macheda had the Bluebirds’ best effort, but his shot was saved by Millers goalkeeper Adam Collin.
Adam Revell hit the crossbar with a header for United in a match of few clear-cut chances.
Rotherham remain one place above the relegation zone in 21st, while Cardiff drop to ninth.
Steve Evans’ side have now gone eight matches without a win in the Championship.
But their hard-fought point at the Cardiff City Stadium extends the gap between them and 22nd placed Brighton, who lost 3-0 at leaders Derby, to two points.
Bluebirds boss Russell Slade, meanwhile, was hoping to exact revenge over the Yorkshire side, who won promotion from League One in the play-off final in May on penalties, when he was in charge of Leyton Orient.
The visitors, who have only won once on the road in the league this season, started the brightest with midfielder Richard Smallwood’s long-range effort going narrowly wide of the Cardiff goal.
Rotherham dominated possession in the first half, but failed to create any real chances of note.
Cardiff also struggled to get going and forced their first corner of the half in the 43rd minute.
After the break United were first to threaten to break the deadlock, as former Manchester United forward Tom Lawrence cut inside the Cardiff penalty area, but saw his effort well held by goalkeeper David Marshall.
Moments later Rotherham’s Argentine midfielder Emmanuel Ledesma, on loan from Middlesbrough, went close, striking a free-kick from 25 yards out, narrowly wide of the Bluebirds’ upright.
Second-half substitute Macheda came on for the largely ineffective Kenwyne Jones and his arrival sparked the liveliest spell of the match as Cardiff pressed forward.
Peter Whittingham and Adam Le Fondre had efforts on goal blocked, before Aaron Gunnarsson’s pass picked out Italian striker Macheda in the area, but his shot was parried away by Rotherham keeper Collin.
The visitors counter-attacked in a breathless passage of play, which ended as Revell headed Smallwood’s cross against the Cardiff crossbar.
