The final round of games in the All-Ireland Senior Football Championship group phase take place this weekend, with four counties set to be dumped out.
The permutations are straightforward in most of the groups. For example in Group 1, the winners of Galway v Armagh will top the group, while a draw would see Armagh emerge on top. And the winners of Derry v Westmeath will finish third, but a draw would be enough for Westmeath.
It's a similar story in Group 2, where the winners of Dublin v Mayo will top the group, but the Dubs only need a draw. Whoever wins between Roscommon, who only need a draw, and Cavan will finish third.

Group 3 is more complicated, with Cork, Tyrone and Donegal all still able to finish first, second or third, with Clare, who are bottom with no points, still able to advance with a win over Donegal, but they would the other game to go in their favour. The standings are currently Cork (4 points), Tyrone (2 points), Donegal (2 points) and Clare (0 points).
Meanwhile, Kerry will top Group 4 with a draw against Louth, both of who are guaranteed to advance from the group. Meath need to beat Monaghan to remain in the Championship.
