Michael O'Halloran could miss St Johnstone's clash with Livingston through injury following his run-in with Scott Brown last week.

The Celtic skipper was cleared by the Scottish Football Association earlier this week after it was ruled the collision which has left the Saints winger with "massive big stud marks" down the side of his hip was accidental.

Callum Booth is also a doubt with a thigh strain, but boss Callum Davidson will welcome back Craig Conway (broken nose) and Murray Davidson (concussion).
