Man of the match
Brendan Murphy (Carlow): Immense performance from the big midfielder, particularly in the hectic closing 10 minutes in which he kept his cool and kicked three of the four points Carlow scored without reply to claim their historic victory.
Brendan Murphy's massive exocet of a sideline kick which soared over the bar from almost 40 metres to reduce Louth's lead to two points and galvanise his team-mates and the Carlow supporters.
Never mind the dismissal of Dessie Finnegan shortly before half-time, the big question was how Louth allowed themselves be second best to the ball through most of the first half. The Wee men only played in spurts, unlike last season.
Derek Fahy won't be a Louth favourite but the huge number of bookings was mainly due to indiscipline by players on both sides who coughed up silly cards. Good co-operation between umpires and linesmen and ref when petty, stupid stuff went on behind the referee's back.
What they said
Luke Dempsey (Carlow manager):
"I'm over the moon for the players because only that group know how hard they've worked. I'm thrilled. It was a huge team effort. For Carlow football, a volcano has erupted."
Peter Fitzpatrick (Louth manager):
"In fairness to Carlow, I have to take my hat off to them. They plugged away and plugged away. They never gave up. It was Carlow's day. I won't take anything from them."
Wides: Carlow 11 (5); Louth 11 (6).
