Kevin Moon and Kenny Deuchar look set to miss St Johnstone's Scottish Cup fifth-round home tie against Dundee United on Saturday.

Moon picked up a hamstring strain in Wednesday night's Co-operative Insurance Cup semi-final against Rangers.

Deuchar was set to train on Friday after missing the Hampden defeat with a back problem, but remains a doubt for Saturday's game, which is likely to come too soon for Collin Samuel (knee).

Kevin Rutkiewicz and Martin Hardie remain sidelined.

Michael Duberry could make his debut after arriving at the club on Friday.

Saints (from): Smith, Grainger, Irvine, MacKay, Morris, Davidson, Millar, Craig, MacDonald, Deuchar, Morais, Milne, Main, Anderson, McCaffrey, Jackson, Sheridan, Reynolds, Duberry.
