Ireland’s Andrew Brace will be in the middle for the last, and certainly not least, of the four heavyweight contests next Sunday (9 April) which pits holders, Stade Rochelais, against three-time winners, Saracens, at Stade Marcel Deflandre.

The EPCR Challenge Cup quarter-finals also get under way on Friday evening when Wayne Barnes of England takes charge of what promises to be a fiercely-competitive head-to-head between the Scarlets and ASM Clermont Auvergne at Parc y Scarlets.

Scotland’s Mike Adamson has been appointed for Saturday’s all-French clash between RC Toulon and holders, Lyon, at Stade Félix Mayol, and later the same day, the Benetton Rugby v Cardiff Rugby, and Glasgow Warriors v Emirates Lions last-eight ties will be refereed by the English pair of Luke Pearce and Matthew Carley respectively.

Following a high-powered start to the knockout stages of the tournaments, EPCR can announce the referees for the quarter-finals of the Heineken Champions Cup and EPCR Challenge Cup who have been appointed by a committee chaired by the organiser’s Head of Match Officials, Tony Spreadbury.
