St Mirren manager Danny Lennon has no fresh injury concerns ahead of the game.
His players came through the weekend action unscathed, meaning the Buddies boss has the option of naming the same side who defeated Rangers in their last outing.
Saints have also been boosted by the return of Hugh Murray, who made his first appearance of the season on Saturday after recovering from knee surgery.
Willo Flood should be available for the game after missing Saturday’s win over Hibernian due to illness.
Forward Lauri Dalla Valle has also been ill this week and is a doubt.
Danny Swanson (knee) has resumed training as he steps up his rehabilitation, while utility man Scott Severin (broken leg) remains out.
