GAA preview: The biggest games this weekend
Michael Bolton
With league finals and relegation now on the radar of teams, the stakes are getting higher in the next round of action in the National Leagues.
In football, Dublin travel to face All-Ireland champions Armagh, with Dessie Farrell's side winning three out of their first four games in Division One.
At the other end of the table, Mayo will be hoping for a win to boost their chances of avoiding relegation when they host Kerry.
Ulster rivals Donegal and Derry clash on Sunday, while Galway will be hoping to continue their impressive start to the season when they face Tyrone.
In Division Two, Monaghan will hope to continue their promotion charge when they travel to Louth, while Cork hosts a Roscommon side also looking for promotion straight back to the top tier.
In hurling, All-Ireland runners-up Cork host Kilkenny, as Clare continue their search for a first win of the season when they travel to Limerick.
