I am aware that there are many things not known about concussion, BUT there are also many things that are known and how serious it actually is, like how long it can take to recover and that some people don't have any symptoms until weeks after the knock. These facts alone should mean that a) a player should be monitored for a significant period following the incident b) dialogue with the player must also be constant for a significant period of time, ensuring his environment is comfortable for him to communicate how he's feeling.
They failed to spot his symptoms for NINE months! They failed to attribute his drop in form following the incident might be a symptom!
Culpability isn't passed over following one visit, it's a potential concussion, it may weeks for symptoms to show, so it should be as above constant monitoring of the player following a knock to the head, this means it's our staff (The Club) that are responsible for him every day.
All I have to go on is a) what I saw of the incident b) the clubs' response and their public statement c) Jan's interview. If a player comes out and says they had symptoms of a concussion for 9 months following a knock to the head and the Club were totally oblivious to it, then unequivocally I'd say we fucked up.
