The final round of All-Ireland SFC fixtures takes place this weekend, with all matches being played at neutral venues.
Here's what's at stake in each group.
Group 1
Group 1 is by far the most intense, with all four counties having the potential to finish first or last.
Tyrone, Cavan, Donegal and Mayo all have two points each going into the finals.
If the teams score the same number of points, which is quite possible in this group, then the key factor will be their personal meetings in previous matches.

Group 2
Group 2 is more predictable.
Kerry and Meath are both still in the running, so their match will decide who finishes top. If Kerry win or draw, they will automatically qualify for the All-Ireland quarter-finals.
If they finish second, they will play a preliminary home quarter-final.
For Meath to move into third place, Roscommon must beat Cork to close the gap to 14 points.
There's a lot at stake in the Roscommon-Cork clash. It's effectively a playoff to stay in the competition, although a draw would also be enough for Roscommon.

Group 3
Group 3 is much more stable than the first two groups.
