Leinster and Munster have discovered their Champions Cup quarter-final referees with Nigel Owens of Wales set to officiate Munster's match with RC Toulon at Thomond Park, while Jerome Garces of France will take charge of Leinster's tie with holders, Saracens at the Aviva Stadium.
Munster will take on Toulon on Saturday, March 31, before Leinster will challenge defending champions Sarries on Sunday, April 1.
Leinster qualified for the quarter-final stages with a perfect record after beating Exeter, Glasgow, Montpellier both at home and away from home, while Munster finished top of Pool 4 with four wins from six with their only defeat coming at the hands of Racing in Paris.
Both sides enter the knockout stages among the tournament favourites after their respective semi-final berths in last year's competition.
Leinster will look to have both Luke McGrath and Sean O'Brien back for the quarter-finals as both players continue to recover from their respective injuries.
McGrath injured his knee in the Blues 20-13 victory over Pro 14 champions the Scarlets a fortnight ago while O'Brien has not played since Leinster's win over Exeter in December as he continues his recovery from a hip injury.
