Saints interim manager Craig McLeish is forced into three changes for our visit to Dundee in the William Hill Premiership.
Alex Gogic misses out through suspension, while Declan John is also unavailable with a hernia problem. Jonah Ayunga suffered an ACL injury in last weekend's defeat to Livingston. They're replaced by Jayden Richardson, Scott Tanser and Roland Idowu.
Liam Donnelly is unable to make it despite returning to training, but Marcus Fraser is back in the squad for the first time since injuring his collarbone our Scottish Cup quarter-final against Partick Thistle almost two months ago.
St Mirren Youth Academy prospects Grant Tamosevicius, Caiden McMillan, Ruari Duff, Thomas Falconer and Luke Douglas all take a place on the bench.
