Ten-man Sheffield Wednesday held off city rivals United to draw their first game under new manager Jos Luhukay.
Owls defender Glenn Loovens was sent off after 64 minutes for a second bookable offence but the Blades, who won 4-2 at Hillsborough in September, could not make the breakthrough.
Visiting goalkeeper Joe Wildsmith made a fine save to tip Clayton Donaldson’s glancing header over the crossbar.
Daniel Pudil had the Owls’ best effort but his 20-yard volley fizzed wide.
They could have sneaked a victory in stoppage time, but Blades goalkeeper Simon Moore made excellent saves to keep out long-range shots from Adam Reach and Ross Wallace.
Dutchman Luhukay, appointed as the successor to Carlos Carvalhal on 4 January, switched to a three-man defence for his first match as a manager in English football.
Despite Loovens’ dismissal for two fouls on United striker Donaldson, his side registered only their sixth Championship clean sheet of the season.
The Blades moved up to sixth in the table with their point, above Leeds on goals scored.
But they could not secure a first Steel City derby double since 2005-06 and have now won only one of their past 10 league games.
Donaldson’s header in the 50th minute was the first effort on target that either side had managed, and although United dominated the latter stages, Wildsmith was largely untroubled.
