St Johnstone manager Derek McInnes has no fresh injury concerns ahead of the game.
Jamie Adams has been struggling with a sickness bug and had been rated doubtful for the visit of the Steelmen but the midfielder is expected to return to training and McInnes is hopeful he will be involved.
Motherwell will again be without Keith Lasley (hamstring) but Steve Jennings has overcome the knock he played through in the victory over Hibernian while Tom Hateley is hopeful of recovering from the calf problem which forced him off.
Bob McHugh is out for six weeks after suffering a wrist injury before being recalled from a loan spell with Partick Thistle after just one day.
