Sunderland slipped to an agonising home defeat at the hands of Crystal Palace on Saturday, despite holding a 2-0 lead after 60 minutes.
A brace of goals from Jermain Defoe either side of the break had put the Black Cats in a commanding position.
But goals from Joe Ledley and James McArthur levelled the tie, before Christian Benteke struck in the 94th minute to condemn the hosts to a fifth defeat in six Premier League matches.
The visitors made a bright start to the game and appeared the most likely to score the first goal, but poor play from Steve Mandanda and Damian Delaney allowed Jermain Defoe the opportunity to hand the hosts the lead.
The second goal came following a period of intense pressure on the Palace goal and, after goalkeeper Mandanda had repelled previous shots, Defoe tapped home from short range to double Sunderland’s lead.
The concession appeared to stir Palace into life and within 60 seconds they were back in the contest thanks to Joe Ledley’s deflected effort, which bounced cruelly past a hapless Jordan Pickford.
McArthur leapt bravely to head home with 15 minutes of the game remaining to level matters, and the contest appeared to be heading for a draw as the clock ticked past the 90-minute mark.
But there was a cruel sting in the tail in the final moments of the encounter, as Benteke rose to head home from a corner that swung towards the edge of the six-yard box.
The defeat, combined with a point for Stoke City at home to West Bromwhich Albion, roots Sunderland to the foot of the Premier League table.
They return to action on Saturday, when West Brom visit the Stadium of Light.
