The Warriors welcome back 10 World Cup-stars to their squad ahead of the Heineken Cup campaign. Also included is Wales and Lions threequarter Dafydd James, who has been playing for the Bridgend club side since his comeback from a long-standing shoulder injury.
Wales Under-21 threequarter Matthew Nutthall is the shock exclusion.
Injuries have robbed the Warriors of the services of back-row man Ryan Jones (fractured scathoid bone in his hand) hooker Andrew Joy (neck inury) and vice captain Richard Bryan (elbow injury).
Christian Loader, who has returned to the Brewery Field after his summer move to Rotherham, is part of the front-row contingent.
The Warriors open their campaign with a home game against Italian outfit Calvisano on 5 December (1915 GMT).
Zurich Premiership champions Wasps and last year's Heineken Cup finalists Perpignan complete the group.
Warriors Heineken Cup squad: Aisea Havili, Brent Cockbain, Ceri Sweeney, Chris Horsman, Christian Balshen, Christian Loader, Cory Harris, Dafydd James, David Bishop, Deiniol Jones, Emyr Lewis, Gareth Cooper, Gareth Thomas, Gareth Wyatt, Geraint Morris, Gethin Jenkins, Jonathan Bryant, Kevin Morgan, Lee Thomas, Maama Molitika, Mark Lewis, Martin Jones, Matthew Rees, Mefin Davies, Nathan Budgett, Neil Jenkins, Nick Kelly, Paul John, Richard Parks, Robert Sidoli, Sililo Martens, Sonny Parker.
