Sullivan the late hero for Drogs
Dundalk, now rooted to the bottom of the table, led 2-0 in the first half and still had a single-goal advantage with four minutes left, but Mick Cooke’s men turned it around with Peter Hynes’s second goal of the night and then Sullivan’s stunning winner.
The Lilywhites got off to a dream start with a goal inside five minutes, Mark Griffin profiting from some slack defending on the right side of before lashing a rising shot past keeper Gabriel Sava.
