North's dreams at a league and cup double have been dashed after they were beaten 3-2 in a thrilling Guernsey FA Cup semi-final by St Martin's.
Saints took the lead after 76 seconds when ex-island captain Matt Warren scored before ex-Guernsey striker Ryan Tippett made it 2-0 after 25 minutes.
But North top scorer Nigel Hutton got one back on 33 minutes before Matt Loaring levelled the tie after an hour.
Chris Mauger sealed a place in the final for Saints with a late winner.
Saints' only win in the FA Cup came in 2005 and they will face the winners of Wednesday's semi-final between Sylvans and Vale Rec.
