For Saturday's British & Irish Cup semi-final, Munster coach Anthony Foley has opted for the wily Mossie Lawlor to man the last line of defence. Lawlor, the current captain of Shannon, won 69 senior caps for Munster.
Eoghan Grace returns to the side having limped out injured when Connacht visited Limerick in February and he links up with Tommy O'Donnell and team captain O'Mahony in what looks a potent back row.
Duncan Williams and Cusack maintain a half-back partnership that has served their side so well in this cross-border competition, while Sean Scanlon, an unused replacement last Sunday, and Barnes have the sort of pace to stretch the Ulster Ravens defence.
Replacements: Dave Kilcoyne (UL Bohemians), Sean Henry (UL Bohemians), David O'Callaghan (UCC), Paddy Butler (Shannon), Conor Murray (Garryowen), Mike Kelliher (Richmond), Luke O'Dea (Shannon).
