Cardiff's bid for a third Challenge Cup title will kick off when they welcome Brive to the capital in the opening round.
EPCR confirmed the rounds of games earlier today, with further details regarding kick off times and broadcasters to follow in due course.
The Blue and Blacks open their campaign against the French giants in front of home supporters at the Arms Park and then face a trip up north to take on Newcastle Falcons the following weekend.
The reverse fixture at home takes place in round three, which falls in January, with the pool stage drawing to a close a week later with a trip to Brive's Stade Amédée-Domenech.
