Sheffield United's promotion push has been given a boost with a 2-1 win at home to Scunthorpe United.
The visitors went ahead after 30 minutes when Mark Duffy's low strike found the bottom corner.
However, they were reduced to 10 men soon after thanks to Sam Togwell's reckless challenge on Michael Doyle.
It took until the 53rd minute for the Blades to make their numerical advantage count as Lee Williamson volleyed into the top corner from close range.
Stephen Quinn's long-range drive 10 minutes from time sealed the win for Danny Wilson's side on a night when city rivals Sheffield Wednesday sacked manager Gary Megson.
