Munster team manager Shaun Payne, however, refused to be drawn on whether or not either would be included in the matchday squad against the Blues.
"At this stage both are included in the extended squad. We'll wait and see how things go in training tomorrow," he said.
"But it has to be remembered that in match terms these two are four games behind the other players in the squad."
Payne confirmed that Paul Warwick is suffering from a foot ligament injury that will keep him sidelined for the next two to three weeks.
In addition, Ian Dowling continues to be troubled by a knee injury with no definite date being given for the Kilkenny man's return.
MUNSTER Squad (v Cardiff Blues): Backs (11) - Danny Barnes, Felix Jones, Scott Deasy, Denis Hurley, Doug Howlett, Barry Murphy, Tom Gleeson, Lifeimi Mafi, Jeremy Manning, Toby Morland, Peter Stringer.
