After the conclusion of the provincial championships, the new All-Ireland championship series will get underway this weekend.
With 16 teams divided into four groups of four, each team will play three games. One at home, one away, and one at a neutral venue.
Top of each group goes through to the quarter-finals, with second place in the group taking on third place in the next group. The groups consist of each provincial winner, the provincial runners-up, the next seven best placed league teams, and 2022 Taliteann Cup winners Westmeath.
On Saturday, All-Ireland champions Kerry will face Mayo in the weekend's standout game. In Salthill, Connacht champions Galway will host Tyrone.
In group four, Donegal will be hoping to get their season back on track when they travel to Clare.
In hurling, Limerick will be aiming to get over their defeat against Clare when they face Tipperary, while the top two in the Munster championship clash as Clare host Cork.
