Connacht, meanwhile, kick off the following day against Montpellier at the Sportsground.

Sarries head for France to face Simon Zebo and co for a mouthwatering curtain-raiser.
Leinster, also in with Lyon and Northampton Saints, welcome Benetton to Dublin. The Irish province will come up against a resurgent Saints in the key December back-to-back games.
Ulster have a home showdown with Clermont six days after their visit to the Rec to square up to Bath.
Connacht have Toulosue away the Friday after their meeting with Montpellier, and can look forward to a pre-Christmas double-header with Gloucester.
