Mackin goal proves the difference
Louth 2-19 Tyrone 2-16
Louth dug deep to record their second victory of the campaign, with Andrew Mackin's second-half goal proving crucial.
Tyrone were out of the blocks quickly and their dominance early on was rewarded after eight minutes when Conor Grogan played the ball off to Gerard Gilmore, who rifled the ball past James Connolly for the game's opening goal.
Louth responded well with three consecutive points, including a long-range beauty from Nigel Stanley.
They finished the half strongly scoring three of the final four points to go in with a 1-11 to 1-8 half-time lead.
The excellent Damien Casey was Tyrone's best player and his unerring accuracy from frees got the Ulstermen back into the game early on in the second half.
However, all Tyrone's hard work was undone after a mix-up in defence allowed Mackin to sneak in and somehow dribble the ball past John Devlin for Louth's second goal.
Louth were now in the driving seat and went four points clear when Ger Smyth sent over an excellent score.
Casey pulled back a goal but Tyrone's fate was sealed when Shane Callan and Liam Dwan sent over close-range points to seal an important win for the Wee County.
