Two-time Heineken champions Munster, who failed to qualify for the knock-out stages of the elite tournament for the first time in 13 years, have an away tie in Brive.
Promoted to the elite group for the first time are Leicester prop Dan Cole and scrum-half Ben Youngs, who have already established their Test credentials, Gloucester prop Paul Doran-Jones, and the uncapped Wasps centre Dominic Waldouck and Leeds flanker Hendrie Fourie.
