ROTHERHAM UNITED conceded two minutes into injury time to lose at Don Valley Stadium against Bristol Rovers.
Andy Dorman struck the goal for the Pirates, which is a blow to the Millers’ play-off hopes.
Naylor, who had been restored to the side in place of Raynes, produced a solid challenge as Rovers opened with an early flurry.
Taylor then made an impact with a ball winning challenge in midfield which saw Revell in space. However, when he tried to find Harrad, Parkes spotted the danger and cut it out.
It also needed a vital intervention by Woodards when Harrad switched play towards Grabban who had moved across to the left after starting on the right.
The Millers began to step things up after a slowish start but then the visitors might have scored.
When the ball was played for Zebroski he looked to be offside and the crowd really showed their feelings when the flag stayed down. The winger got away from Griffiths and as Mullins challenged, he struck a fierce shot into the side netting.
When Revell helped the ball on, Harrad had half a yard on his defender but he got squeezed for space and keeper Bevan was able to check the shot with his leg.
Rovers should then have been in front.
Carayol made tracks into the area, drove the ball across where Zebroski was under pressure as he tried to finish off inside this six yard area. The ball ran quickly to Lund and from only a couple of yards he put the ball wide.
Rovers. who have improved since Mark McGhee took over half a dozen games ago, wasted a decent opening.
Zebroski did the work on the right, pulled the ball back but Anyinsah miskicked completely.
When Grabban whipped in a free kick from the left, Woodards got his head on it and the ball flew not far wide of the far post.
Rotherham managed a real danger moment when Mullins played a splendid ball for Grabban on the left. He cut inside two challenges and his shot was deflected just over with the keeper beaten.
Andy Scott made a change at the break, replacing Harrad with Cadogan. He went on the left with Grabban down the middle.
An immediate corner saw Cadogan get a second chance to deliver. It went to the far post where Mullins rose well for a header but Bolger headed away.
Warrington timed his advance perfectly to go down at the feet of Carayol who was chasing a long ball.
Then Rotherham had a great opportunity to take the lead.
Revell played a ball beyond the defence. Grabban used his pace to get away but as the keeper came forward the Millers top scorer put his shot wide of the far post.
A fine last minute save by Warrington to turn over Brown shot seemed to have secured the Millers a point but DORMAN fired the winner for Rovers two minutes into stoppage time.
