O'Driscoll captains a side that shows several changes from the one that started against Sale Sharks last time out. as coach Tony McGahan omits players who have been involved in almost all of Munster games to date. McGahan recognises the task his squad faces on Saturday.
"There are no more formidable places to go than Ravenhill and we fully recognise that. Ulster are a tough, robust side. But we have full confidence in our squad, in their ability to put their best foot forward to defend the good form we've shown up to now."
Munster: D Hurley; A Horgan, B Murphy, L Mafi, I Dowling, P Warwick, P Stringer; F Pucciariello, D Fogarty, T Buckley; M O'Driscoll capt, D Ryan; A Quinlan, J O'Sullivan, J Melck. Replacements: J Flannery, D Hurley, M Melbourne, J Coughlan, M Prendergast, J Manning, K Lewis.
