Scottish Professional Football League clubs have voted to approve the use of concussion substitutes.
The new rule will come into force on a trial basis next month and should then be extended for the remainder of the season.
The new ruling would allow teams to make two additional substitutes if a player has to go off with a serious head knock.
Scotland 42 senior clubs backed the change that was initially proposed by the International Football Association Board (IFAB) back in December 2020, that the system could be trialled between January and August 2021.
SPFL chief executive, Neil Doncaster said: “The safety and wellbeing of players is clearly of the utmost importance to everyone involved with running football.
“Monday’s tragic news that Gordon McQueen has been diagnosed with dementia is the latest reminder of why it is vital that we do everything we can to protect those playing our game.
“We have seen a great deal of positive development in concussion protocols across sport in recent years and we hope that our participation in this trial will be the next step in that process.
“The Scottish FA refereeing department has already started briefing our clubs on the details of the rule change, with that process continuing in advance of the change coming into force on 6 March.”
When a concussion substitute is used, the opposing team has the option to use an additional substitute for any reason.
