The winners of the play-off matches, which will be played at the home venues of the top two finishing sides in the regular Magners League table, will then meet in the Magners League grand final on Saturday, May 28 (kick-off 5.05pm).
The venue of this season's Magners League grand final will be determined by the results of the semi-finals.
The honour of staging the grand final will go to the team that has the highest regular season league ranking once the two finalists are known - it will be Munster if they win their game or the winners of the other semi-final.
Information on ticketing for both semi-finals and the Magners League grand final will be available on the respective team websites and also on www.magnersleague.com.
