Managerless Sunderland followed last week's 6-0 humiliation at Bolton with a 2-1 humbling at home to bottom-of-the-table Doncaster Rovers.
The Black Cats let down a crowd of more than 38,000 who had turned out to welcome returning hero Jermain Defoe, who re-signed for the club on deadline day.
But while there were cheers for Defoe, there were boos at half-time and full-time after Sunderland turned in another awful performance.
