Motherwell will assess full-back Jake Carroll ahead of the Ladbrokes Premiership contest with Kilmarnock.
The Irishman went off with an ankle knock at Ibrox on Sunday but the injury is not as bad as first feared.
The pair both suffered hamstring injuries in their win over St Mirren and will undergo scans to assess the extent of their injuries.
Striker Osman Sow remains out with an ankle complaint.
