Scottish Premiership clubs have approved a temporary rule change to allow the use of up to five substitutes this season.
The rule will come into effect this weekend for the opening Scottish Premiership fixtures and means clubs will be able to name nine players on the bench and use five of them but only at three intervals during the game.
SPFL chief executive Neil Doncaster said: “As excitement builds ahead of the return to competitive action this weekend, I am pleased that the Premiership clubs have approved this resolution which was recommended by the board.
“Player welfare was at the forefront of our decision to recommend this change and it is vital that we recognise the additional strain being placed on players as we embark on the 2020/21 season.
“We are preparing similar resolutions for the Scottish Championship, League 1 and League 2 and these will be distributed to the clubs in those divisions in due course.”
