Ten men, one potentially vital point ... on-the-whistle report: Hull City 0 Rotherham United 0
A goalless draw at midtable Hull City was a creditable result for the depleted Millers in their first match back from the international break, particularly as they had a player sent off in the second half.
However, a win for third-bottom Huddersfield Town means Matt Taylor's side are now only two points clear of the relegation reckoning, although they do have a game in hand on the Terriers.
January signing Domingos Quina came on after the interval for only his second outing and lasted for just ten minutes before receiving a straight red card for bringing down clean-through Adama Traore who had looked certain to score.
Rotherham held on bravely in the closing stages and remain in 20th spot with eight games of the run-in still to negotiate.
The visitors were looking for their first away victory since their famous triumph at Sheffield United back in November - a run stretching to ten winless matches on their travels.
Early on, they offered little more than resolute defending as the home side dominated possession and territory.
Fifteen minutes had passed before there was any sight of goal, Regan Slater cutting in from the left and drilling a low shot wide for the Tigers.
Rain had fallen heavily before and after kick-off, creating a slippy surface at the MKM Stadium as the Millers began to make their presence felt in the opposition half by forcing three corners in quick succession.
At the other end, Viktor Johansson, back on club duty following his first Sweden call-up, had to be at his sharpest to foil Ryan Longman who was trying to bend the ball into the far corner after being slipped in on goal by Traore's pass.
The ground was close to full capacity, with Rotherham selling out their allocation of 2,000-plus tickets and the home attendance reaching its highest figure for nearly six years.
As half-time approached, Shane Ferguson failed to make the most of a dangerous low cross from Tariqe Fosu, managing onlyl tame contact from only a few yards out.
The loan man's probing delivery was out of keeping with the poor quality of too many of Rotherham's balls into the box.
A goal would have flattered the Millers but they went in at the break deserving to be level.
Ollie Rathbone's groin injury hadn't healed sufficiently enough for the midfielder to be included in the squad and there was no place either for recent arrival centre-half Tyler Blackett.
Cohen Bramall came in at left-back and there was a midfield start for Jamie Lindsay.
Hakeem Odoffin dropped to the bench where there was a welcome spot for Quina who had been restricted by knee trouble to one substitute appearance since his loan switch from Watford.
Following a slow start to the second half, the visitors almost paid the price for their lack of directness.
They spent too much time passing and not crossing on the edge of the Hull box and a City breakaway finished with Ozan Tufan hitting the bar after Johansson had parried Lewie Coyle's right-flank supply.
Quina came on and almost made an instant impact with a free-kick whipped in from the left that Jordan Hugill headed towards goal only for a Hull body to deflect the ball for a corner.
His next contribution led to his exit and he was more relieved than anyone when Malcolm Ebiowei blazed the ensuing free-kick over the bar.
Rotherham saw out the contest as Alfie Jones shot wastefully over and the point could turn out to be a crucial one.
But Huddersfield, under old Millers saviour Neil Warnock, are closing.
