The PRO14 takes place between September and May, with the PRO14 teams split into two conferences. Each conference contains two Irish and Welsh teams and one team each from Italy, Scotland and South Africa. The PRO14 teams then play each team in their own conference home and away and play each team from the opposing conference once, either at home or away. At the end of the conference stage, the top three PRO14 teams from each conference advance to the play-offs, with the conference winners gaining a bye to the semi-finals, which they host. The final is then played at a pre-arranged venue.
At the conclusion of the competition, seven teams qualify for the Heineken Champions Cup. The top three PRO14 teams from each conference qualify for the tournament and the fourth-placed teams in each conference enter a play-off for the seventh spot. However, South African teams are excluded from this because they’re ineligible for European competitions.
Since 2001, Irish teams have dominated PRO14 rugby. Leinster are the most successful team in the tournament with seven titles, and Irish rugby teams have won the PRO14 final on 12 occasions. By contrast, no team from Italy or South Africa has ever appeared in the PRO14 final.
