A SPFL spokesman said: “Fifa has allowed each league to determine its own rules regarding substitutes since the Covid-19 pandemic began.
“As a members’ organisation, it is key that clubs in each division are able to make decisions on issues such as this for themselves.”
The system was used in three of the four SPFL leagues – the Championship being the lone exception – last term in order to help clubs cope with the demands of the ongoing pandemic.
Premiership clubs took the decision last month to bring forward their winter break after crowd restrictions were put in place following the spread of the Omicron variant in Scotland.
It was announced earlier this week by First Minister Nicola Sturgeon that those restrictions will now be lifted, starting with Celtic-Hibs on Monday.
