Karius had a concussion per the head of rehab/ concussion specialist Doc at Mass Gen- probably the worlds's premier hospital. Has anyone here had a concussion? You are really in no position to be playing after one of any severity. Your spatial awareness/ reflexes/ cognition are all impaired. This really would explain what happened to Karius. Shame on UEFA and us for letting him down IMO. He should not have been allowed to play on without being examined. Also, the turd Ramos should have been off or at least retrospectively been banned. I'm loving how fans of the club that believes in YNWA are treating him.
