Football continues to be an absolute disgrace across all sports when it comes to how seriously they treat head injuries. And the long term effects of dementia etc there-in.
We've suffered personally on the biggest stage of all with the terribly lax attitude from both our medical team and UEFA in allowing Karius to play on in the European Cup Final whilst concussed. 4 years on, and the PL/ UEFA/ FIFA/ CAF et al are still as haphazard when it comes to the seriousness of this issue that most every other sport is on top of and treating with the utmost priority.
Until a proper concussion protocol is put in place, and this is taken out of the clubs/ countries/ players hands, football will continue to literally play with guys lives.
There need's to be independent neurologists at every game. With an observer in the stand to give details to him of the ferocity of the incident/ impact. Then, if ANY clash of heads occurs, you take both players off the pitch to a secluded area for a proper evaluation. Like a good 10 mins or whatever the medical recommendation is. Not the farcical minimum on pitch eval currently in place. That's where you use a concussion sub during that time. If the players are then fine to return then sound. If not, you play on with the concussion sub.
It’s not hard. Football continues to be an absolute out laying disgrace in doing the absolute bare minimum when it comes to head injuries across all sports.
