It's set up for a Leinster-Munster Heineken European Cup semi final at the Aviva Stadium on Sunday April 27th.
That's if both teams win their quarters at the weekend.
Taking that Leinster get the better of Toulon on Sunday in France and Munster lose, then it's Leinster against Toulouse in the Aviva on the 27th.
If Leinster lose and the Reds win, it's Munster against Toulon at the Stade Velodrome in Marseille on Saturday April 26th.
If Ulster beat Saracens they play Clermont Auvergne or Leicester at the Aviva on the 26th.
