Matty Pearson struck in the closing seconds as fourth-tier Accrington dumped Lancashire neighbours and Premier League newcomers Burnley out the EFL Cup in the second round.
Pearson averted a penalty shootout in the last minute of extra-time at the Crown Ground, sweeping home from a goalmouth scramble to secure a 1-0 win, a major scalp and local bragging rights.
The Clarets have now lost at this stage for three years running but would have averted a shock result this time had substitute Andre Gray finished a fine late chance at the end of 90 minutes.

Burnley's fellow top-flight new boys Middlesbrough were also dumped out in extra-time, Fulham coming from behind to win 2-1.
Boro have claimed four points from their first two games this term but were undone by their Sky Bet Championship opponents at Craven Cottage.
David Nugent put the visitors in front after just eight minutes only for Scott Malone to level early in the second half and Lasse Vigen Christensen to win it with 113 minutes on the clock.
Adnan Januzaj's first goal for Sunderland handed David Moyes his maiden competitive victory as the Black Cats edged past League One Shrewsbury and into the third round.
The 21-year-old needed 83 minutes of a largely turgid cup tie to find his range, blasting a right-footed shot past keeper Jayson Leutwiler to spare a crowd of just 13,979 at the Stadium of Light further punishment on a night when victory was the only option.
Bournemouth registered their first win of the season as Marc Wilson's fine strike saw them overcome League Two table-toppers Morecambe 2-1 at the Globe Arena.
Republic of Ireland defender Wilson marked his first appearance since re-joining the Cherries last week with his first goal since scoring against the Faroe Islands in 2012, firing in from considerable range in the 54th minute.
That was after Morecambe had swiftly cancelled out Max Gradel's eighth-minute opener through Cole Stockton, and then almost gone ahead in first-half stoppage time when Tom Barkhuizen hit the post.
The draw for the third round of the EFL Cup is:
Nottingham Forest v Arsenal
Leeds v Blackburn
QPR v Sunderland
West Ham v Accrington
Southampton v Crystal Palace
Swansea v Man City
Fulham v Bristol City
Bournemouth v Preston
Tottenham v Gillingham

Derby v Liverpool
Northampton v Manchester United
