Millwall made it a hat-trick of victories at Pride Park as a Shaun Hutchinson goal gave them a 1-0 Sky Bet Championship win over Derby County.
The defender headed home in the final minute of the first-half to give The Lions all three points.
Gary Rowett was able to welcome Murray Wallace back into the squad - and starting XI - for the trip to face The Rams, with former Derby stars Alex Pearce, Mason Bennett and George Evans also present in the line-up.
Nathan Byrne returned to the starting line-up for Wayne Rooney’s side having missed out in the draw against Barnsley to a knock he picked up in training. He replaced Andre Wisdom in the starting line-up with the captain's armband going to Colin Kazim-Richards for the first time.
Martyn Waghorn also returned to the starting XI, replacing Lee Gregory who picked up a knock in training.
The Rams lack of cutting edge in the final third
The opening 20 minutes saw Craig Forsyth come close twice for the Rams. After nine minutes, he was open at the back post for when Byrne whipped in a cross from the right. The full-back powered a header towards goal, but it went straight into the hands of Bartosz Bialkowski.
Seven minutes later Byrne and Kamil Jozwiak combined down the right flank which allowed Byrne to be set free and fire in another cross to his fellow full-back who this time dived to send his header just wide.
For the remainder of the half, Derby maintained the lion’s share of possession but struggled to find the quality in the final third. Jozwiak came the closest with fewer than five minutes left to play when he created space on the edge of the box and rifled a shot towards the bottom corner which the Lions’ goalkeeper palmed away.
Millwall score with only shot on target
With one minute left in the first half, Millwall took the lead with their first and only shot on target of the game. A free-kick into the area was cleared for a corner. The resulting in-swinging set piece from Jed Wallace found Hutchinson who punished poor defending in front of goal converting a free header into the back of the net past home keeper Kelle Roos.
After heading into the dressing room moments after going a goal being, the Rams were up against a Millwall side that would look to sit back even more than than they did in the first half.
The Rams had nothing to show for their dominance in possession
Athough Derby had the majority of possession, they could not break down a disciplined Millwall side.
A couple of chances fell to the Rams around the hour mark. A free kick was awarded down the right flank in a dangerous position after both Byrne and Jozwiak were brought down as they looked to combine. Waghorn delivered the ball into the area and it was headed clear as far as Jason Knight.
From 20 yards out, the midfielder drilled an effort through the crowded area and it whistled past the far post.
Moments later, Jozwiak worked the ball well in the area before finding Graeme Shinnie on the edge of the box who was quickly fouled. Kazim-Richards stood over the set piece, but fired into the wall.
The Lions look to play on the counter-attack and defend their lead
County almost got caught on the counter-attack inside the first 10 minutes when Millwall broke down the left before feeding to Ben Thompson who had plenty of space in the right of the box. Rather than take the shot, he back-heeled to Wallace but Shinnie was able rush in to intercept and clear the danger from the edge of the box.
As Millwall continued to sit back, the Rams couldn't find the equaliser and will look to bounce back when they return to Pride Park on Tuesday night to face Brentford.
Byrne shines, substitutes make positive impact
With just over 10 minutes left to play, Derby came agonisingly close from a brilliant inswinging delivery from Byrne from a corner. It was met by substitute Louie Sibley’s run at the far post. He beat Bialkowski, only to be denied by the cross bar from close range.
Another substitute, Patrick Roberts, cut in on his left foot before striking at Bialkowski seconds into four minutes of stoppage-time but the stopper claimed with ease, with referee Darren England blowing the whistle for full-time shortly after.
Wayne Rooney's side edging back into a relegation scrap
A 17th loss of the season sees Derby drop to 19th in the Championship, seven points above the relegation zone, while Millwall move up to 10th.
Managers' post match reactions
Derby County manager Wayne Rooney told BBC Radio Derby:
"I thought we played well in terms of we got the ball into very good areas, we controlled the game and didn't concede chances.
"I think the problem today was we didn't have the hunger to score goals.
"Up until we got to their penalty box I thought we played quite well. As soon as the ball went into the box if you're not prepared to get your body across players and want to go and score then you're not going to."
Millwall manager Gary Rowett told BBC Radio London:
"It was a tight game, I just felt as though we'd watched a lot of Derby, they matched up our formation and we've seen them score a lot of set-piece goals but not that many from open play.
"It's getting to a point now where virtually anyone who's fit usually starts for us.
"We've just got to do what we've got to do and sometimes we have to be a little bit gritty away from home.
"When you go 1-0 up it really was there for us to just protect it and see if we could see the game out in a comfortable way, and I thought we did, I didn't think Derby really caused us any problems, they had one shot that hit the bar, but that's the only one I can really remember."
