Munster head coach Anthony Foley has made four changes to the side that defeated Zebre for this Sunday's visit of Ospreys .

Three of those changes are seen in the pack with Dave Kilcoyne and Mike Sherry returning to the front row alongside John Ryan who remains at tighthead.

Dave O'Callaghan makes his first start since returning from an adductor injury at openside. Billy Holland remains as captain and blindside flanker with Jack O'Donoghue making the positional switch to number eight for the first time this season.

The only change across the backline comes at scrum half with Duncan Williams returning to partner Ian Keatley in the half-backs.

Rory Scannell and Francis Saili form the centre partnership for the seventh consecutive game.

Development prop Peter McCabe is included in his first Pro12 squad after being named amongst the replacements.
