Blackburn prodded the dying embers of their promotion hopes and found a faint glow.
The odds remain stacked against Rovers snatching the final Championship play-off spot but Hayden Carter's first goal for the club at least kept hopes alive.
Rovers in ninth go to sixth-placed Millwall on the final afternoon next Monday two points behind. Sunderland and West Brom also have 66 points, but Rovers' negative goal difference is another handicap.
In short, a repeat of this fixture in the play-off semi-finals later this month is a long shot.
But in a finale of unexpected excitement after a largely profligate and lifeless performance, Rovers took a point when Carter headed in a Sorba Thomas corner on 86 minutes.
