Dundee United are set to have an unchanged squad. Midfielder Ryan Gauld returned from a hip problem when he came off the bench midway through the second half of United's midweek defeat by St Johnstone. John Souttar was again an unused substitute after being troubled by an Achilles injury while fellow defender Curtis Good (hip) remains out.
Former Manchester United midfielder Eric Djemba-Djemba is struggling for St Mirren with a tight groin, but Gary Teale is back in the squad ahead after recovering from a bone problem. Still out for the Buddies are hernia victim David van Zanten and skipper Jim Goodwin, who completes a two-game ban.
