Ireland internationals Mike Haley and Dave Kilcoyne are among three Munster changes for Saturday's BKT United Rugby Championship showdown against Glasgow Warriors at Thomond Park (5.15pm, live on RTÉ2 and RTÉ Player).
Jack Crowley also comes in as Patrick Campbell, Antoine Frisch and Josh Wycherley drop out from the side that beat Scarlets 49-42 earlier this month.
Frisch is unavailable due to a low-grade leg injury, but is expected to return to training next week.
Haley starts at full-back for the first time since January on his return from an ankle injury with in-form wingers Calvin Nash and Shane Daly starting on either flank.
A new centre partnership sees Crowley and Malakai Fekitoa team up in midfield for the first time with Paddy Patterson and Joey Carbery in the half-backs for the fourth successive game.
Kilcoyne, Diarmuid Barron and Roman Salanoa pack down in the front row with Jean Kleyn and Fineen Wycherley combining for the fourth game in-a-row in the engine room.
The back-row of captain Jack O’Donoghue, John Hodnett and Gavin Coombes is again unchanged.
In the replacements, Scott Buckley, Stephen Archer, Craig Casey, Rory Scannell and Simon Zebo join the squad with RG Snyman set for his second appearance of the season.
