The Clarets’ woeful recent record in the Carabao Cup was extended by another shock defeat as League One Sunderland came from behind to book their place in the third round.
Sean Dyche’s men looked as though they would avoid a sixth successive exit to a lower ranked side when Jay Rodriguez put them ahead just 12 minutes in.
The summer signing first made his name as a Burnley player with some high-profile goals as the Clarets reached the semi-final of the competition in 2009.
But this time his first goal since re-joining the club turned out to be only a false dawn as Sunderland rode their luck to level before the break through Will Grigg and then deservedly completed the upset with quick-fire strikes from Tom Flanagan and George Dobson at the start of the second half.
