After defeats to Edinburgh and the Ospreys, the reigning league champions will be keen to get back to winning ways ahead of next week's interprovincial derby against Leinster.
McGahan's squad assembled for the first time since the World Cup in Limerick yesterday and they trained this morning at Thomond Park, with indications being that most of those involved in the World Cup will see action on Friday in Cork.
After training, the Munster head coach confirmed that hooker Mike Sherry (ankle) will be out of action for between six and eight weeks.
Sherry, who sustained the injury playing for Garryowen in the Ulster Bank League, joins David Wallace, Troy Smith, Felix Jones, Jerry Flannery, Peter Borlase and Darragh Hurley on the province's injury list.
