Leinster and Toulon will meet in opening game of the Heineken Champions Cup round of 16, on Friday April 2nd.
The pair are set to face off with a 5.30pm kickoff on Good Friday after full match details were revealed by tournament organisers this afternoon.
With seven Heineken Champions Cup titles between the pair, the winner will be the first team to advance to this season's quarter finals.
And they will find out their opponents 24 hours later when the Exeter Chiefs host Lyon at Sandy Park at 5.30pm on Saturday the 3rd.
Meanwhile the huge clash of Munster and Toulouse has been set for Saturday the 3rd of April, with a 3pm start at Thomond Park.
The winner is set to face either Wasps or Clermont in the last eight; one of those sides will already be in the quarter finals by the time Munster and Toulouse get underway, with a 12.30pm kickoff that afternoon at the Ricoh Arena.
Ulster and Connacht have also found out their kick-off times for the Challenge Cup last 16.
Both teams have been given 8pm starts, with Connacht taking on the Leicester Tigers at Welford Road on Saturday the 3rd, before Ulster travel to London to face Harlequins on Easter Sunday, also an eight o'clock start.
Should Ulster come through the challenge of Harlequins, they will be up against either the Dragons or Northampton Saints, with their game taking place at 5.30pm on Saturday the 3rd.
Connacht's reward if they can get the better of the Tigers would be a home tie against either the Ospreys or the Newcastle Falcons, who also meet on the Saturday afternoon at 3pm.
