THE NEW CHAMPIONSHIP FORMATS EXPLAINED
Leinster and Munster will run their championships on a round-robin basis, with each team getting two home games and two away.
The top two teams in each will proceed to the provincial finals, with the third team in each getting a chance to earn a place in the All-Ireland quarterfinals, by beating the winner or losing finalist in the Joe McDonagh Cup, the new next tier down from the Liam MacCarthy itself.
The Leinster and Munster winners go to the All-Ireland semi-finals, the losers of the deciders go straight to the quarter-finals.
The team that finishes fifth in Leinster will not play in the Leinster Championship in 2019 —they will be replaced by the winner of the Joe McDonagh Cup, unless the winner of that cup is Kerry, who would then play off against the last team in Munster for the right to go into the southern championship next summer.
In the football, there are round-robins too. Instead of having knock-out AllIreland quarter-finals, the eight best teams in the country will now play three matches at that stage, one in Croke Park, one home and one away.
Group 1: Munster Champions; Connacht champions; Ulster runners-up or the team that beats them in Round 4 of the qualifiers; and Leinster runnersup or the team that beats them in Round 4.
Group 2: Ulster champions; Leinster champions; Munster runners-up or the team that beats them in Round 4; and Connacht runners-up or the team that beats them in Round 4.
The top two in each group advance to the All-Ireland semi-finals — Winners of Group 1 v runners-up of Group 2; winners of Group 2 v runners-up in Group 1.
In the event of three or more teams finishing on the same number of points, scoring difference will count. If two teams finish level on points, the outcome of the match between them will decide who advances.
Provincial games in both codes, with the exception of finals, will have 20 minutes of extra time (10 x 2) in the event of a draw. All games in the football qualifiers and the preliminary hurling quarter-finals must finish on the day. If the sides are level after 30 minutes of extra time (2x10 and 2x5) a 45m (football) or 65m (hurling) freetaking competition follows. If the sides are level after five shots it will go down to sudden-death.
