St Johnstone manager Derek McInnes has no fresh injury worries.
His players came through last week's draw against Kilmarnock unscathed, allowing him to name a similar side for the visit of the Paisley Saints.
Kevin Moon is back in training after almost a year on the sidelines with a cruciate ligament injury but the game comes too soon for him.
Michael Higdon and Marc McAusland are back in contention for St Mirren.
Higdon has returned to training following a knee injury while McAusland has overcome a foot problem.
Nick Hegarty, Garry Brady and Gareth Wardlaw remain on the sidelines for the Paisley side.
