Director of Rugby Rassie Erasmus has named his match-day 23 for tomorrow's round 5 Champions Cup game against Glasgow Warriors at Scotstoun Stadium (5.30pm).
There are four changes to the side that defeated Racing 92 last weekend with three in the pack and one in the backline.
In the front row loose-head prop Dave Kilcoyne starts this weekend with Niall Scannell and John Ryan continuing at hooker and tight-head respectively.
Behind them sees Donnacha Ryan switch sides in the second row with the Tipperary lock joined by Jean Kleyn, who has overcome last week's illness to make his first European start for the province.
Jack O'Donoghue takes the place of the injured Tommy O'Donnell in the back row as captain Peter O'Mahony and CJ Stander continue at blindside and number 8.
