Captain Rachel Malcolm is missing through injury as Scotland make four changes for the Women's Six Nations meeting with Italy on Saturday.
Evie Gallagher makes her first start as she replaces Malcolm in the back row.
Prop Megan Kennedy is fit again, Sarah Law comes in at fly-half and there is a place for winger Liz Musgrove.
Helen Nelson takes over the captaincy and moves from number 10 to inside centre, with Hannah Smith involved with the GB Sevens camp.
Uncapped duo Evie Wills and Coreen Grant are among the replacements.
Scotland: Rollie, Musgrove, Thomson, Nelson, Gaffney, Law, McDonald; Bartlett, Skeldon, Kennedy, Wassell, McMillan, Gallagher, McLachlan, Cattigan.
Replacements: Rettie, Cockburn, Muzambe, Belisle, Howat, Maxwell, Willis, Grant.
Italy have made two changes from their 67-3 defeat against England last weekend.
Vittoria Ostuni Minuzzi, who was due to start against England but was withdrawn at the last minute, gets the nod at full-back which means skipper Manuela Furlan moves to the wing and Aura Muzzo drops to the bench.
The backline is otherwise unchanged with Maria Magatto completing the back three, Beatrice Rigoni and Michela Sillari forming the midfield partnership and Sara Barattin and Veronica Madia as the half-backs once more.
In the pack, Melissa Bettoni returns to start at hooker, causing Lucia Cammarano to shift from No.2 into the back row as Giada Franco misses out.
Italy: Ostuni Minuzzi, Furlan, Sillari, Rigoni, Magatti, Madia, Barattin, Skofca, Bettoni, Gai, Fedrighi, Duca, Arrighetti, Cammarano, Giordano.
Replacements: Turani, Maris, Tounesi, Locatelli, Veronese, Sgorbini, Stefan, Muzzo.
