The Premier League is set to introduce concussion substitutions.
Top flight sides are expected to vote through trials at a meeting on Wednesday which would see each club permitted to make an additional two changes per game.
The Football Association had wanted to introduce the measures in the recent third round ties but did not receive full protocol from lawmakers the International Football Association Board (IFAB) in time.
The Premier League is set to introduce two concussion substitutions into the game
It is understood that the Premier League want two substitutions, rather than one, to cover the likelihood of a clash of heads between team-mates. The arrivals could come in as early as next week, although no final decision has been made on timelines.
Feedback will subsequently be given to IFAB ahead of their annual general meeting in March.
Sportsmail’s campaign for football to tackle its dementia problem, has called for the introduction of temporary, rather than permanent, concussion substitutes.

Experts, including Dr Willie Stewart, whose groundbreaking study uncovered alarming evidence of increased rates of neurodegenerative disease in former players, believe that bringing in temporary changes already in place in other sports including rugby union, allow medics extra time to assess injured parties.
Dr Stewart believes that permanent subs ‘change nothing’ as there is currently no barrier to players coming off with a suspected head injury.
Instead he feels that temporary subs would allow doctors to properly assess those who have been subjected to head trauma.
