Nick Fenton saw red as the Millers were held to a draw at Don Valley, despite leading 2-0 with half an hour left.
Aaron Webster and Greg Pearson cancelled out two goals from November Player of the Month nominee Adam Le Fondre. Le Fondre had put the Millers two-up with a penalty followed by cheeky tap-in after half-time.
Ronnie Moore made just one change from the side that was beaten at the New Meadow on Tuesday night, Andy Nicholas dropped to the bench, handing Stephen Brogan his first league start of the campaign.
Both sides found it hard to take control of the opening moments and little was created, with the exception of Tom Pope's turn and shot on five minutes, but Albion goalkeeper Shane Redmond collected the ball comfortably.
Following some neat work on the right by Adam Rundle and Gary Roberts, the ball found its way right to Mark Lynch whose cross was met by Le Fondre, but his looping header was again caught with ease by Redmond.
The visitors began to get back into the game soon after, Steve Kabba's snapshot had to be tipped wide, and from the resulting corner, Russell Penn volleyed over with his left foot. Burton won two more corners soon after, the first one led to a scramble with Kabba seeing his shot saved, before John McGrath fired narrowly over after the Millers had failed to clear.
On 35 minutes, Kevin Ellison slipped Le Fondre through, but his path was blocked by the onrushing Redmond. The ball rebounded out to Nicky Law whose shot was blocked six yards out by Tony James leading to handball appeals around the ground. Referee Mr. Hooper wasn't interested and the ball was cleared, much to the displeasure of the home support.
Two minutes later, and this time the Millers were awarded a penalty. After Pope had headed Rundle's corner across goal, Albion only half cleared, and as the ball came back in towards Ian Sharps a Brewers arm connected with the ball, allowing Le Fondre to smash the ball down the middle from 12 yards.

The Millers began the second half on top, Pope and Rundle both having efforts blocked after Le Fondre's lob from 25 yards rebounded off the crossbar.
As the visitors pushed forward, Roberts and Law were given much more time in midfield, and their link play with Le Fondre was a joy to watch. Pope could have then doubled the lead on 58 minutes, but he couldn't beat Redmond after Le Fondre had squared for him. Rundle found space, but was denied, and Roberts resulting shot was cleared off the line by Brewers skipper Darren Stride.
As the game reached the hour mark a second goal appeared inevitable for the Millers, as Ellison dragged wide, Le Fondre again the provider. Sharps laid off for Rundle, whose shot blazed over the bar, before a mix-up in the defence allowed Le Fondre to double the lead. Lynch took a quick throw on the right to Rundle, whose low cross was left by Stride, but the lively Le Fondre showed his predatory instincts to pounce on the error and poke the ball past Redmond.
The Brewers hit back immediately, after Kabba had mis-kicked Pearson's cross, the ball found Webster at the far post who cut inside and blasted the ball past Andy Warrington and Sharps on the line.
On 71 minutes Fenton lunged at Webster on the half-way line, and there were few complaints from the centre-half when Mr Hooper showed him the red card.
Burton began the search for an equaliser, and Keith Gilroy should really have done better when he headed over at the far post, when he was left unmarked. On 85 minutes the equaliser finally came, Pearson was allowed too much time in the area and his shot on the turn beat Warrington and nestled in the corner.
Substitute Marc Joseph headed over Law's corner late in the game, but the Millers were left ruing their missed chances as the game came to a close.
