Chesterfield 0-2 Burton Albion
Adam McGurk's brace sealed all three points for Burton Albion as League Two leaders Chesterfield lost their second home game in a row.
McGurk's first came from a low shot from 12 yards after 10 minutes and he headed his second minutes later from Chris Hussey's right-hand cross.
Robbie Weir should have made it three soon after but missed an open goal from close range.
Jay O'Shea's late shot was the closest the home side came to a consolation.
Chesterfield remain top of the table on goal difference while Burton climb to 12th and are now two point off the play-off places.
VIEWS FROM THE DRESSING ROOM
Burton Albion manager Gary Rowett told BBC Radio Derby:
"It's a very, very difficult place to come. Paul's produced a fantastic team, but we were magnificent today.
"I said before the game that I'd like to lose a game and say the opposition were much, much better than us, but I think again, we were absolutely fantastic.
"In truth, we could probably have won it by three or four. I know that might flatter us slightly, but we had some terrific chances and the game plan worked fantastically well.
"To come here and to do that, I thought was absolutely magnificent."
