The Premier League have confirmed today that clubs are to be allowed to use permanent concussion substitutes as part of an ongoing trial.

Clubs have agreed to take part in an initiative approved by the International Football Association Board in December.

It means teams will be allowed to make a maximum of two concussion substitutions each.

The additional concussion substitutions may be made regardless of the number of substitutions a team have made already.

A Premier League statement said: "Premier League Shareholders today formally agreed to introduce the International Football Association Board's (IFAB) additional permanent concussion substitutions trial."
