Battling Millers closing in on safety ... on-the-whistle report: Norwich City 0 Rotherham United 0
A strong defensive display laid the foundations of a result that keeps them in 18th spot and increases the gap between them and the drop zone to four points.
The Millers, who have six matches left to negotiate, also have a game in hand over all the teams below them except Cardiff City.
Their dogged character and willingness to put their bodies on the line made them full value for their share of the spoils.
Rotherham were without Viktor Johansson who had been a second ever-present this term. The goalkeeper missed out because of an injury picked up in training and was replaced by Josh Vickers who was appearing in a league match for the first time in more than a year.
The stand-in showed no sign of rustiness in the fourth minute as he dived full length to push away Sam McCallum's fierce drive and followed that up soon afterwards by getting down quickly to a Josh Sargent shot.
It was all Norwich in the opening stages, with Gabriel Sara flashing an effort wide before Teemu Pukki was off target as the visitors struggled to get out of their own half.
The rain had fallen heavily prior to kick-off but the sun was out by the the teams did battle on a windy day at Carrow Road.
On 24 minutes, the Millers had a clear sight of goal but Tariqe Fosu couldn't get the right connection on Jamie Lindsay's low cross and scuffed ball over the bar from close range.
McCallum wasn't far away from distance as the half-hour mark came and went with Rotherham defending solidly as they remained under pressure.
Conor Coventry fired over the bar from just outside the box in the 35th minute before more resistance at the other end foiled Sargent as the Canaries man shaped to shoot.
On the stroke of half-time Jordan Hugill, playing against his former club, flung himself at a corner but it was the Millers striker who finished up in the back of the net rather than the ball.
Midfielder Ollie Rathbone was back in the starting line-up after his impact off the bench in Good Friday's 3-1 win over West Brom and Cohen Bramall was preferred at left-back to Leo Hjelde.
Tyler Blackett was selected at centre-half in the injury absence of Bailey Wright while Fosu moved from midfield into the front three, with Shane Ferguson dropping to the bench.
Blackett cleared off the line ten minutes into the second half after Onel Hernandez had made inroads on the left side of the penalty area as the Millers continued to hold firm and look for opportunities on the break
Most of the action was still in their territory and Vickers beat out Sara's shot before Pukki directed the ensuing corner just wide.
For the rest of the contest Matt Taylor's men were more than equal to the Canaries' threat and Coventry even found time to test Angus Gunn with a low, skidding shot.
Wes Harding kept out Christos Tzolis' shot on the line in added time and the same Norwich player then blazed wide.
Rotherham deserved their point - and also the standing ovation they received from the away contingent at the end.
