St Johnstone are boosted by the return of David McCracken.
Defender McCracken missed the weekend win over Motherwell but is back in contention for the visit of the Buddies, although Kevin Moon is a slight doubt with a shoulder injury.
Jody Morris (hamstring), Sam Parkin (ankle), Callum Davidson (calf) and Murray Davidson (knee) all remain on the sidelines.
St Mirren have an unchanged squad for the game.
Aaron Mooy (back) and Hugh Murray (knee) are still building up their fitness following injury.
Darren McGregor is also out following cruciate ligament damage.
St Johnstone (from): Enckelman, Maybury, Wright, MacKay, Anderson, Adams, Craig, Millar, Haber, Moon, Sheridan, Higgins, Sandaza, Gibson, McIntosh, May, Mannus, Caddis, McCracken.
St Mirren (from): Samson, Mair, Van Zanten, Haddad, Tesselaar, Teale, Goodwin, Thomson, Hasselbaink, Thompson, McGowan, McAusland, McLean, McKee, Carey, Barron, McShane, Smith.
