Aberdeen could have Gary Naysmith and Ryan Jack back in their squad - manager Craig Brown believes the pair are close to full fitness after returning to training following lengthy absences. Andrew Considine (broken leg) and Chris Clark (broken ankle) are out for the rest of the season.
Buddies boss Danny Lennon has no fresh injury worries and could name a similar squad to the one which defeated St Johnstone last week. Darren McGregor (knee) and Thomas Reilly (ankle) remain sidelined.
