Fabian Schär was allowed to carry on playing for Switzerland after being knocked unconscious in a Euro 2020 qualifier.
Concussion – also known as minor head injury – is commonly caused by falls, road crashes, assaults and sports accidents. Each year, approximately a million people attend A&E departments in the UK following a head injury, with the majority of these injuries being classed as minor.
The effects of concussion can leave people with symptoms including dizziness, nausea, confusion or an inability to process or retain information, sensitivity to light, and vision distortion, and therefore it is important to seek immediate medical attention.
This was not the case for Schär, as he continued to play during the Switzerland v Georgia game on Saturday.
It is clear that more needs to be done in football to respond to head injuries that may cause concussion.
