I'm not sure that's right. Looks like 48 hours after a diagnosis at minimum so we'll see. Wemby doens't have a history of concussions AFAIK so that should point to a faster recovery given that it wans't that severe of an impact. I think more of the location of the hit being right on the chin which the impact sends a signal for the shut down. Its why boxers always aim for that, but its not necessarily a severe concussion by any stretch.
That being said I want them to be as safe as fucking possible with this. Concussions are fucking scary and I dont' think they should fuck around at all with it. IDGAF about the series compared to this dudes brain.
