Peter Haring is set to make his Hearts comeback against St Mirren at Tynecastle on Saturday.
The Austrian has missed the last seven weeks following hernia surgery but is in Craig Levein's squad preparing to host the Buddies.
Ben Garuccio sits out through suspension after being sent off against Motherwell last week, while full-backs Michael Smith (thigh) and Demetri Mitchell (knee) remain on the sidelines.
Provisional squad: Doyle, Godinho, Brandon, Berra, Souttar, Shaughnessy, Bozanic, Djoum, Mulraney, Lee, Clare, Haring, Morrison, Naismith, MacLean, Vanecek, Ikpeazu, Keena, Cochrane, Zlamal.
