Andrew Browne (Achilles), Eoin Griffin (hamstring), Johnny O'Connor (facial fracture), Rodney Ah You (foot) and Frank Murphy (groin) are still not in contention, though some of them hope to be available for selection next week.
This will not worry head coach Eric Elwood, however, as there is only one change to the starting line-up for the trip to the Welsh capital.
The westerners will field a hugely experienced pack backed up by a youthful and dynamic back-line marshalled by full-back and captain Gavin Duffy.
CONNACHT (v Cardiff Blues): Gavin Duffy (capt); Fetu'u Vainikolo, Kyle Tonetti, David McSharry, Tiernan O'Halloran; Niall O'Connor, Paul O'Donohoe; Brett Wilkinson, Adrian Flavin, Ronan Loughney, Michael Swift, Mike McCarthy, John Muldoon, Ray Ofisa, George Naoupu.
Replacements: Ethienne Reynecke, Denis Buckley, Stewart Maguire, David Gannon, Michael Kearney, David Moore, Matthew Jarvis, Henry Fa'afili.
