All eight players saw action for Ireland in last weekend's Six Nations defeat to England at Twickenham.
Also included in Munster's extended panel is hooker Jerry Flannery who is returning to Munster senior action for the first time since the Heineken Cup game against Wasps.
Flannery did have a run-out with the Munster 'A' side against Leinster 'A' last week and was particularly prominent when Munster had their final run-out ahead of Saturday's game, at training in Garryowen on Thursday.
Back rower Denis Leamy is currently nursing a shoulder injury, which he sustained against England, and he misses out this weekend.
Fans should note that Saturday's game is a sell-out at Musgrave Park and there will be no tickets available for purchase on the night or beforehand.
MUNSTER Squad (v Ulster): Backs (12) - Denis Hurley, Shaun Payne, Brian Carney, Ian Dowling, Doug Howlett, Kieran Lewis, Rua Tipoki, Lifeimi Mafi, Paul Warwick, Ronan O'Gara, Tomas O'Leary, Peter Stringer.
