Jack Colback's 95th-minute equalizer piled more misery on Cardiff City as Sunderland came from behind to claim a 2-2 draw on Saturday.
The Welsh side looked to be in complete control in its first game following the sacking of boss Malky Mackay by controversial club owner Vincent Tan, after Jordon Mutch had opened the scoring with a deflected strike after just six minutes.
Three points appeared to be a formality when former Sunderland man Fraizer Campbell struck in the early stages of the second half.
But Sunderland refused to lie down, and found some hope when Steven Fletcher pulled a goal back with seven minutes left to set up a frantic finish.
There was still time for more late drama and the comeback was completed with the last meaningful kick of the game when Colback found the net with a deflected effort to spark jubilant scenes in the away end and leave the Premier League's bottom side just two points adrift of safety.
