Scott Fardy’s Leinster toppled reigning Champions Cup winners Saracens in their quarter-final overnight.
Fardy, who has been playing almost exclusively lock in Ireland, switched to blindside flanker for Leinster in the big win.

Leinster 30 - Saracens 12
Scarlets 29 - La Rochelle 17

Ben Mowen played at six for Pau, as the French side ended the reign of Stade Francais in their Challenge Cup quarter-final.
