Here are the fixtures and dates for the football and hurling league semi-finals
It was a hectic final day across all the divisions but particularly in Division One, where a late Monaghan win helped condemn Cork to
Cork came into their final game away to Kerry with very faint hopes of a semi-final place, but a 0-20 to 1-12 defeat - coupled with wins for Monaghan and Mayo over Donegal and Down respectively - saw the Rebels relegated.
That means that Cork and Down will be replaced in Division One next season by Tyrone and Cavan, who beat Galway 1-16 to 1-12 in what amounted to a promotion playoff.
Elsewhere, Kildare and Clare were promoted to Divison 2 while Laois and Armagh will be playing Division 3 football, with the O'Moore County losing heavily to Meath by 0-18 to 1-9 at home while Kieran McGeeney's men went down despite a 1-18 to 0-15 win over Derry.
And finally, Antrim and Louth secured passage to the third division while Westmeath and Limerick fell through the trapdoor to Division Four.
The Division One semi-finals will take place next weekend, with Dublin taking on Donegal, and Kerry clashing with Roscommon.
