MARK Beevers hit the bar and Gary Taylor-Fletcher fluffed a late chance as Millwall were held to a draw at Cardiff.
A point in South Wales could prove valuable in the Lions' battle against relegation but they will reflect on what might have been after a couple of near-misses.
Beevers had goalkeeper David Marshall beaten but his rising drive rattled the woodwork before bouncing down just in front of the goal-line.
And when substitute Ricardo Fuller broke through in the 87th minute, he cut the ball back to Taylor-Fletcher who looked primed to score but missed his kick.
The gap between Rotherham and Millwall is now down to four points but victory for second-bottom Wigan over Brighton kept the Latics' survival hopes alive.
The Lions now travel to Blackburn Rovers on Tuesday night.
Neil Harris was forced to make three changes to his starting XI at the Cardiff City Stadium – two enforced by injury, one by suspension.
Ed Upson, who was sent off against Wigan in midweek, made way for Martyn Woolford on the right side of midfield.
Shaun Cummings and Shaun Williams both missed out through injury, prompting recalls to the line up for Alan Dunne and Nicky Bailey.
Former Millwall left back Scott Malone started for the hosts and his outswinging cross was glanced wide by Joe Mason at the far post inside the opening 90 seconds.
Craig Noone then volleyed well over the from the edge of the box as the Bluebirds looked to apply some early pressure.
Sid Nelson made a vital interception inside his own box to divert the ball out of Mason's path and into the grateful arms of David Forde.
The Lions' first shot in anger came in the 11th minute when Bailey took aim from distance and fired well over the bar.
Woolford then saw an effort deflected behind for a corner which was taken short to Dunne, whose looping cross into the box was headed clear by Bruno Ecuele-Manga.
Sean Morrison headed over from a corner before Noone, after beating Dan Harding and Mark Beevers, crossed into a dangerous area, with Nelson on hand to nod the ball away.
On the half-hour mark, an opportunistic Harding half-volley took a wicked deflection off Morrison but, fortunately for the Bluebirds defender, the ball ricocheted away from goal rather than towards it.
Aiden O'Brien almost caught Marshall out with a cross-shot which floated just beyond the top corner, before Cardiff wasted a golden chance to break the deadlock on the break.
Eoin Doyle led the charge and, after skipping past Beevers, his pass across the six-yard box, which only needed a tap-in, somehow avoided teammates at both the near and far post.
In the dying minutes of the half, Joe Ralls' cross drifted onto the bar, O'Brien played in Martin for a shot which Marshall held comfortably and Alan Dunne's 30-yard drive was saved.
Five minutes after the restart, Gregory touched the ball off to Beevers inside the box and the defender's snap-shot crashed into the underside of the bar.
Ten minutes later, Martin dispossessed Morrison near the byline, allowing O'Brien to pick up the loose ball, but the youngster couldn't find Gregory or Woolford in the middle.
Bluebirds boss Russell Slade introduced Anthony Pilkington from the bench and the winger almost made an instant impact, drifting into a pocket of space on the edge of the box but shooting over.
Harris brought on Fuller and Taylor-Fletcher for the final 15 minutes and the duo almost combined to score the winner.
Fuller won a footrace with Manga to get in behind the defence and his cut-back was perfectly-weighted for Taylor-Fletcher, but the striker failed to make contact with the ball with the net waiting to bulge.
And when Dunne's teasing cross eluded both Woolford and Fuller at the far post, the Lions knew their chance to seal back-to-back wins had gone.
