My point exactly. There is no way he should have continued without proper assessment, which cannot be done at pitchside
Agreed. It has happened at least twice during the World Cup, both in games involving England. Too often players with head injuries are being allowed to stay on the FOP only to be removed a few minutes later when it becomes clear that they should not continue, simply because of the substitution Laws. Somewhere down the line an avoidable tragedy will occur as a result. Until the Laws change, medical staff need to be more responsible and get players off.
