St Johnstone striker Cillian Sheridan will return from a hamstring injury for the game against the Buddies. Midfielder Murray Davidson is a doubt, however, with a minor knee problem. Striker Sam Parkin (ankle) remains on the sidelines. St Mirren boss Danny Lennon meanwhile expects Jeroen Tesselaar to shrug off a knock. The Dutch defender picked up the injury in the Scottish Communities League Cup quarter-final defeat by Ayr United in midweek but is expected to train today. Hugh Murray (knee), Aaron Mooy (back) and Darren McGregor (knee) remain on the sidelines. St Johnstone (from): Enckelman, C Davidson, Maybury, Mackay, Anderson, Morris, Gibson, Craig, Moon, Millar, Sheridan, Sandaza, Haber, Caddis, May, Mannus, Durnan, M Davidson, Wright. St Mirren (from): Samson, Van Zanten, McAusland, Mair, Tesselaar, Thomson, Hasselbaink, Goodwin, McLean, Teale, Carey, Thompson, McGowan, Graeme Smith, Barron, McKee, McShane, Haddad.
