Michael Lowry (neck and concussion), and Stewart Moore (concussion) were both injured during Saturday's round 15 defeat at Leinster. Both players will be unavailable for selection this week.
Stuart McCloskey (groin), Rob Herring (calf), Callum Reid (knee), and John Cooney (ankle) are all injury doubts for this weekend's fixture against Hollywoodbets Sharks.
Their fitness for selection will be assessed through the week.
