You would be through to the Preliminary QF. Group winners advance automatically to the QF and await the 4 winners of 2nd place v 3rd matches.It look's like we'll have Kerry joining Mayo and Louth in our group. That'll be a tough one indeed! I presume it's the top two that go through to the next stage?
Edit: I just found out that the top three advance from the groups, so if we beat Louth then we're through to the next stage.
