The SFA have confirmed they will trial an extra substitute rule in the Scottish Cup should any player suffer a concussion or suspected serious head injury.

The International Football Association Board (IFAB) approved the trial in which any player with an actual or suspected concussion will be immediately subbed off and replaced by another player via, if necessary, a further substitute.

The governing body for Scottish football confirmed it will begin to introduce the sub trial in the Scottish Cup as early as possible.

John MacLean, Scottish FA Chief Medical Consultant, said: "This is an important step in the progress that is being made across sport surrounding head injuries. The introduction of a permanent concussion substitute in football would build on Scotland’s world-leading approach on the subject of head injury and trauma in sport. 

"Implementing the trial in the Scottish Cup will in turn provide invaluable data to inform a wider implementation plan for Scottish football."

It comes as ex-footballers including former Celtic striker Chris Sutton have called for tougher regulations and further help for players to prevent detrimental effect on brain function down the line including dementia.
