Sunderland produced the biggest shock of Wednesday's second-round action, dumping out Premier League side Burnley 3-1 at Turf Moor despite falling behind to Jay Rodriguez's first goal since re-joining the Clarets.
Will Grigg equalised for the Black Cats before Tom Flanagan and George Dobson struck in the first five minutes of the second half to complete the comeback for Jack Ross' unbeaten League One side.
Sunderland's reward is another clash with Premier League opposition, having drawn Chris Wilder's newly promoted Sheffield United at Bramall Lane.
