A penalty apiece from Ian Robinson and the Magpies’ Luke Brodie saw the scores level at the break. Lukas Franzen-Jones restored the Dockers’ lead five minutes in to the second half.
But, at the death, Jack Frankland’s cross found Tadley Bromage who powered home to force penalties. And Loxwood keeper Fraser Trigwell was the hero as he kept out Newhaven's sudden death spot-kick to see the Magpies through to the final.
Loxwood will play the winners of tonight's semi-final showdown between Lancing and Lingfield.
Photographer Phil Westlake was at Worthing's Woodside Road to capture the drama, Here are a selection of his pictures.
