Nigel Clough's Burton side have not scored in their past two matches
Play-off hopefuls Millwall scored two goals in six first-half minutes to beat League One leaders Burton Albion and go fifth in the table.
Albion would have regained a four-point lead over second-placed Wigan Athletic with a victory but, despite a bright start, they trailed when Aiden O'Brien crashed the ball into the top corner.
Lee Gregory made it 2-0 when he scored after rounding keeper Jon McLaughlin.
Clear chances were scarce after the break and the Lions held on.
Burton Albion manager Nigel Clough told BBC Radio Derby: "I thought we started brilliantly in the first 10 minutes or so.

"We had two or three situations and a great chance to score, and then we just got caught out with two balls over the top.
"It's because we were attacking. If you're attacking it's very difficult for the back four to be on the edge of our own penalty area."
