Paul McComiskey came on as a substitute for Down

Sub Jamie Carr hammered a first-half goal to put Louth into a lead of 1-4 to three points.

But just before the break Down hit the net through a Kevin McKernan penalty which had been awarded against Alan Page for a third-man foul.

Down clawed their way back and scores from Ronan Murtagh, John Clarke and sub Paul McComiskey saw them claim the win.
