Meanwhile, if Roscommon beat Cork they will be promoted to the top tier. And likewise for Cavan against Tipperary. Louth are already relegated and if Down beat Meath, the Royals will join them in Division Three next year.
In Division Three the winner of Longford and Fermanagh will join Armagh in sealing promotion, while a Laois win in Division Four will secure their passage to the third tier.
Wins for Roscommon, Cavan, Down, and Laois will also avoid any further disruption to the Division Two and Four final fixture dates. Because last weekend’s postponed fixtures in those divisions will not need to be played.
