St Mirren striker Curtis Main will miss the visit of St Johnstone in the cinch Premiership on Wednesday night.
The striker suffered a reaction after coming on against Hibernian at the weekend.
Dean Lyness picked up a knock in training, Eamonn Brophy remains out with an ankle injury and on-loan Hibs midfielder Alex Gogic returns after being ineligible against his parent club.
St Johnstone striker Chris Kane faces a knee operation and is unlikely to play again this season, while midfielder Melker Hallberg is suspended.
Michael O’Halloran is rated “touch and go” by manager Callum Davidson, and recently-signed strikers Nadir Ciftci and Theo Bair will miss the trip to Paisley but should be back for next week’s trip to Aberdeen.
Longer-term injury victims Shaun Rooney, Craig Bryson and David Wotherspoon all remain sidelined.
