Sheffield United have been denied the chance to go top of the English Championship by rivals Sheffield Wednesday as the Steel City derby finished goalless at a rain-soaked Bramall Lane.
True to form, the home side dominated for lengthy periods in front of a crowd of more than 30,000 on Friday but, David McGoldrick's first-half penalty miss aside, they were unable to turn the lion's share of possession into presentable chances.
Their one clear opportunity came and went after 14 minutes when McGoldrick's tame effort from 12 yards was saved by Cameron Dawson after Morgan Fox had fouled Mark Duffy in the box.
Wednesday defended stubbornly and routinely had all 11 players entrenched in their own half as they avoided a fifth straight defeat.
Blades boss Chris Wilder made three changes to the side beaten 1-0 at Nottingham Forest last time out, with Chris Basham, McGoldrick and Duffy going in for Martin Cranie, Paul Coutts and Leon Clarke.
Under-pressure Wednesday manager Jos Luhukay also rang the changes after a 4-0 thumping at the hands of Norwich gave them their fourth straight defeat.
Fox, Jordan Thorniley, Ashley Baker and Michael Hector replaced Liam Palmer, Daniel Pudil, Josh Onomah and Atdhe Nuhiu in the Owls starting XI.
