Waterford's Jack O'Donoghue will miss Munster's clash with Scarlets in the Guinness PRO14 at Thomond Park tomorrow.
The back-row has aggravated an existing neck injury.
There are five changes to the side that secured a bonus-point win away to Zebre last week.
Billy Holland returns to captain the Reds with Chris Farrell back from international duty, as Dan Goggin, Kevin O’Byrne and Stephen Archer also return to the starting 15.
