Connor Smith could make his St Johnstone debut if the paperwork is completed following his move from Hearts. Nicky Clark, Chris Kane and Kerr Smith trained on Friday after missing the midweek draw with Aberdeen. Ali Crawford, Sam McClelland and Drey Wright are still not ready to return while Cammy MacPherson and Ross Sinclair are long-term absentees.
Motherwell could have New Zealand international Callan Elliot and Sam Nicholson in their squad but both are short of match fitness. Shane Blaney and Dan Casey and are back on the training pitch but might not be ready while Jon Obika and Callum Slattery remain out.
Did you know? The home side has not won the past seven league meetings of St Johnstone and Motherwell.
