Jersey are through to the quarter-finals of the FA Inter-League Cup after beating the Amateur Football Combination 2-1 away in extra-time.
Playing at Sutton United's ground, Martin Cassidy's side fell behind with fifteen minutes to go but hit back through Arthur Illingworth to stay in the contest.
Karl Hinds was sent off early in extra-time but Jersey found a way to win, Luke Campbell converting a penalty with six minutes to go.
It means they progress to the last eight of a competition they won in 2011/12 with the eventual winners set to represent England in a UEFA tournament.
Guernsey - also one-time former winners, however, are out after going down 5-4 on penalties against the Dorset Premier League at the Track.
Charlie Pinsard's team dominated the early exchanges, racing into a 2-0 lead in front of a healthy home crowd.
But the visitors turned things around with three goals either side of half-time, before Joe Alvarez levelled with his head for Guernsey's Priaulx League squad.
The home side looked most likely to find a winner but it did not come and in the end Josh Concanen's well-saved penalty was all that separated the teams on a disappointing afternoon for the islanders.
