Alex Neil’s side started superbly against the Blades but Dan Neil’s red card just after the half-hour mark turned the tide.
Two goals either side of half-time put the hosts ahead but Lynden Gooch’s superb chip gave Sheffield United lots to worry about before they could secure all three points.
Defeat to the Blades was the first time since February that Sunderland left the pitch without at least a point.
Neil’s side were roared on by a fantastic away following and despite the game being played on a Wednesday night and in-front of TV cameras, that didn’t stop a hardy bunch of Black Cats supporters making their voices heard.
