The Premier League have applied to football's lawmakers IFAB to introduce temporary concussion substitutes from the start of next season.
In a letter written to IFAB on their behalf from FIFPRO and the World Leagues Forum, it is hoped that the Premier League – along with Major League Soccer in the United States and France's Ligue 1 – can become football's first top-flight divisions to trial the protocol.
It is not yet known if the request will be ratified or turned down, with a response from IFAB's decision makers expected in March.
