Premier League clubs are set to be allowed two additional concussion substitutions.
Top flight bosses agreed to introduce the new "additional permanent conscussion substitutions" rule as a trial today - though a start date is yet to be set.
The latest news, which will of course affect Everton and Liverpool, comes amid growing concerns about the impact of head injuries and heading the ball in football.
The new substitution rule will be introduced over a trial period and will allow teams to make two changes in a match for players suspected of or who have suffered with concussion, in addition to three substitutions already allowed.
A statement read: " Premier League Shareholders today formally agreed to introduce the International Football Association Board's (IFAB) additional permanent concussion substitutions trial.
"The trial will be confirmed when the implementation of the reporting processes, including private medical information, has been resolved with IFAB and FIFA.
"With player welfare the Premier League's priority, the protocols will allow a maximum of two concussion substitutes to be used per team, with the opposition side able to use the equivalent number.
"The additional concussion substitutions may be made regardless of the number of substitutions a team have made already.
"The trial is a result of the IFAB's consultation with stakeholders and recommendations from their concussion expert group to allow additional substitutions for players with actual or suspected concussion."
