- Concussion subs trial extended over lack of evidence
- Campaigners criticise Ifab but it says more help is needed
Doctors and coaches failing to remove players with obvious concussions from the pitch has hampered the progress of protocols to prevent traumatic brain injuries, football’s law-making body has claimed.
The International Football Association Board (Ifab) announced on Monday that trials of permanent concussion substitutions would be extended for a year until 2023, saying a lack of consistent action from clubs, combined with difficulties obtaining medical information, meant there was not enough data to “form a scientifically valid decision”.
