David Connolly's injury-time leveller capped a battling Sunderland comeback to claim a point at Burnley.
Connolly struck from 25 yards as the Clarets surrendered a two-goal lead.
Burnley went ahead after nine minutes when Kyle Laffert scored from just inside the area and scored with another clinical finish in the 52nd minute.
Sunderland were outplayed, but Grant Leadbitter set up a tense finish with a fine strike 10 minutes from time, leaving Connolly to snatch a point.
Burnley manager Steve Cotterill:
"We did enough to win the game and two mistakes cost us.
"The game was going nowhere and if it was going anywhere I thought we were going to score another.
"But it can come back to bite you sometimes and you just have to take it. With the goals coming so late it's just a real sickener."
Sunderland boss Roy Keane:
"It was a disappointing performance. If you start slowly and give away a sloppy goal, you're going to have a hard day.
"You can't keep giving yourselves a mountain to climb like we do.
"To be fair to the players they keep climbing them but we hope to make it a little bit easier."
