Stephen Quinn scored late on to give Sheffield United a narrow victory over 10-man Scunthorpe at Bramall Lane.
The Iron took the lead through Mark Duffy, whose low shot from inside the area beat goalkeeper Steve Simonsen.
The visitors lost Sam Togwell after he was dismissed for a challenge on Michael Doyle and the Blades equalised through Lee Williamson who volleyed in.
And Quinn struck the winner from a long-range effort as Danny Wilson's men consolidated second place in the table.
VIEW FROM THE DRESSING ROOM
Blades manager Danny Wilson told BBC Radio Sheffield:
"It was a very big win for us, without playing well in the first half. Scunthorpe played very well in the first half. We didn't really have any tempo and you have to put that down to how well they played.
"They passed it well, they pressed us hard, they didn't let us settle on the ball. Our passing was a little pedestrian at times.
"But then there was a sending off and I think, quite honestly that changed the game."
Iron manager Alan Knill told BBC Radio Humberside:
"It was a great performance. It's tust the result that's not great.
"As a manager or coach, I don't think you could ask any more of the players. I thought they were excellent from start to finish.
"Obviously, we're going to say the sending-off changed the game. I thought we were in control and looked threatening, and then we went to 10 men."
