Holders Saracens will face top seeds Leinster in a mouthwatering European Champions Cup quarterfinal.
Saracens, courtesy of a 62-14 victory against Northampton in their final Pool 2 fixture on Saturday, scraped through as third best runners-up.
And they will now head to Dublin on the weekend of March 31-April 1 in the highlight encounter of this season's last-eight phase.
Leinster and Saracens have won five European titles between them, and Saracens' hat-trick bid is still alive despite last weekend's draw against Ospreys appearing to severely dent their hopes.
Saracens are the tournament's only English survivors, with their qualification avoiding a wipeout for the first time in the 21 seasons that England have had top-flight European representation.
Elsewhere, Leinster's fellow Irish heavyweights Munster will have home advantage against Toulon following a 48-3 thumping of Castres on Sunday, while in-form Scarlets entertain Champions Cup debutants La Rochelle and there is an all-French clash between Clermont Auvergne and Racing 92.
