Football's lawmaking body has agreed to trials of 'concussion substitutes' at 'all levels of the game' following increasing concern for players, who suffer head injuries.
A meeting of the International Football Association Board held on Wednesday approved trials of substitutions, where a player is concussed, or concussion is suspected.
Trials can begin from January in which permanent substitutions can be made if medical staff are concerned about a player.
The move comes after a sickening clash of heads between Arsenal's David Luiz and Raul Jiminez, which left the Wolves man with a fractured skull.
