It means the Amlin Challenge Cup semi-final line-up will look like this:
Friday, 26 April at Stade Aimee Giral, Perpignan (K-O 9.00pm local time)
Perpignan v Stade Francais Paris
Saturday, 27 April at RDS, Dublin (K-O 2.30pm local time)
Leinster Rugby v Biarritz Olympique
The winners will meet at the RDS, Dublin, on Friday, 18 May (K-O 8.00pm local time), and whoever survives from the first semi-final, Perpignan or Stade Francais Paris, will be chasing their first European trophy.
The quality of the semi-finalists is underlined by the fact all four teams have played in the Heineken Cup final before - Perpignan in Dublin in 2003, Stade Francais Paris in Paris in 2001 and Edinburgh in 2005, Biarritz Olympique in Cardiff in 2006 and Paris in 2010 and Leinster in Edinburgh in 2009, Cardiff in 2011 and Twickenham in 2012.
Leinster are the only one of the teams to have won the Heineken Cup, in all three of their finals, and they will be playing the reigning Amlin Challenge Cup holders in Biarritz Olympique. Stade Francais Paris were beaten finalists in the Amlin final in Cardiff in 2011.
