Rob Penney has made one change to his Munster side to face Edinburgh on Sunday in the Heineken Cup at Thomond Park.

This week there is a switch at tight-head prop with Stephen Archer starting next to Damien Varley and Dave Kilcoyne in the front row, as BJ Botha moves to the replacements.

Paddy Butler, named on the bench, is also included in a Heineken Cup squad for the first time since injuring his thumb against the same opposition in October. 

Butler most recently made his return to action starting against Connacht in the league and last week played the full 80 for the Munster A's at St. Mary's RFC.  

Munster:  Felix Jones; Keith Earls, Casey Laulala, James Downey, Johne Murphy; Ian Keatley, Conor Murray; Dave Kilcoyne, Damien Varley, Stephen Archer; Dave Foley, Paul O'Connell; Peter O'Mahony (cpt), Tommy O'Donnell, James Coughlan.
