Warriors have been drawn alongside local rivals and last season’s champions Gloucester Rugby in Pool 4 of the 2015/16 European Rugby Challenge Cup.
Dean Ryan’s men will also travel to France to face La Rochelle and have a trip to Italy to look forward to as Zebre complete the pool.
Warriors return to European Rugby after securing an instant return to the Aviva Premiership with victory over Bristol Rugby in the Greene King IPA Championship final last month.
It means supporters will be able to see at least four derbies against Gloucester next season as Warriors aim to make their mark in the European Rugby Challenge Cup.
