Match ends, Scunthorpe United 1, Burton Albion 0.
Burton's League One title push faltered as they were beaten away at Scunthorpe.
Both keepers were forced into good saves, as Joe Anyon denied Burton's Callum Butcher, before Jon McLaughlin kept out Jordan Clarke's effort.
Neal Bishop gave Scunthorpe the lead from close range after David Mirfin headed down from a corner.
Brewers' Tyler Walker had penalty appeals turned down before Anyon saved again from Butcher as the Irons deservedly took all three points.
Burton are still six points clear of third-placed Bradford but are now without a win in four matches.
Scunthorpe boss Graham Alexander told BBC Radio Humberside:
"I thought the first half was a little bit scrappy and we knew of Burton's threats - they're a very good team.
"We knew what they were about but we wanted to impose our game on them and we spoke at half-time about what it would take to win this game.
"I thought the second half was superb and there's three or four lads holding their legs there at the end - every single one of them put effort into the game."
Burton boss Nigel Clough told BBC Radio Derby:
"I thought we did well first half. Not too bad. We had chances again throughout the whole game but I thought for an away performance first half, we were nice and solid.
"There was nothing in it so we were quite happy at half-time.
"I thought the way we started the second half, for 20 minutes, cost us the game."
