Substitute Sonny Carey’s late winner sent National League side King’s Lynn into the FA Cup second round for the first time in their history as they recorded a 1-0 shock victory against League Two Port Vale

The game looked to be heading for extra-time when teenager Carey pounced in the 82nd minute after latching on to a pass from Adam Marriott.

Another youngster, goalkeeper Archie Mair, had pulled off a number of stunning saves to deny Vale, who were left cursing their missed opportunities.

The visitors should have taken the lead in the 25th minute when Jamar Lozar made a great run from inside his own half and sent Simon Power through – but, with just Vale goalkeeper Scott Brown to beat, he placed his shot wide.

Mair, on loan from Norwich, twice denied Tom Conlon and also made a stunning save to tip David Worrall’s swerving effort around the post as the Linnets, managed by former Norwich defender Ian Culverhouse, advanced at Vale’s expense.
