Scottish clubs outside the Premiership will not be required to test their players for Covid-19 when they resume training.
Sides in the Championship, League One and League Two can return from Monday.
But while Premiership teams are in a testing bubble with two checks each week, this will not apply to the other 30 sides.
Only if friendlies or full training matches are played before 14 September will twice-weekly screening start.
The Scottish FA suspended all football below Premiership level on 13 August following Covid-19 rule breaches by players from Aberdeen and Celtic.
That will now be lifted in line with updated Scottish government advice, and youth and non-professional training will also be permitted.
