LONDON (REUTERS) - The English Premier League said it had agreed to introduce an additional permanent concussion substitutions trial following a shareholders meeting on Wednesday (Jan 20).

The decision comes after the game's rule-making body IFAB last month gave the go-ahead for trials of additional "concussion subs".

Under the protocols teams will be allowed a maximum of two concussion substitutes each per game in cases of head injury.

The trial will allow an additional concussion replacement, regardless of the number of substitutions a team has made.

"The trial will be confirmed when the implementation of the reporting processes, including private medical information, has been resolved with IFAB and FIFA," the league said in a statement.

Earlier, soccer's world governing body said it will trial concussion substitutes at next month's Club World Cup in Qatar.
