Hugo Lloris' injury at the weekend has caused quite a stir.
The French international was knocked unconscious on Saturday after colliding with Romelu Lukaku's knee, and then insisted that he see out the remainder of the match, defying Spurs captain Michael Dawson, and club doctor Shabaaz Mughal in the process.
Fortunately the France captain underwent a CT scan after the game which showed no lasting damage.
Since then, Tottenham manager Andre Villas-Boas and English football as a whole has been bombarded with criticism for the way it deals with head injuries.
The likes of FIFA and brain injury charities have all said their piece, on what they feel was 'irresponsible' behaviour.
However The Lilywhites manager defended his decision, speaking after the match, he said: "When you see this kind of assertiveness from the player it means that he is able to carry on.
"It was my call to delay the substitution, you have to make a decision in situations like this."
The confusion surrounding the saga is caused because of the ruling politics in the game.
On one hand FIFA's chief medical officer claims that the player should have been removed from play, stating that there was a "99 per cent probability" that the player would have been concussed.
Professor Jiri Djorvak continued to say that FIFA's guidelines say if there is any doubt about concussion then the player should be removed from the field of play.
The FIFPro medical advisor also commented on the incident, stating: "The health and safety of the players should be the number one priority and should prevail against any other matters."
This comes as no surprise as FIFA, the international governing body of association football, held a conference regarding concussion just last year, and earlier this year updated it's guidelines which are followed by the FA, the governing body of football in England.
On the other hand when you read the FA's guidelines, they specify "All Clubs shall ensure that any player having left the field of play with a head injury shall not be allowed to resume playing or training without the clearance of a qualified Medical Practitioner." In accordance to these guidelines AVB has done nothing wrong. Which is why you can understand he may feel a bit hard done by.
The question that seemingly doesn't have an answer is which governing body is correct? and who should the football clubs abide by in future?
Concussions in football are particularly rare, but you only have to look back to Carlo Cudicini and Petr Cech's famous incident to remind you of the damage that can be caused. Which is partly down to why head injuries are now treated so seriously.
At the present time concussion is a hot topic in sport, with Rugby experts calling to form a concussion awareness programme at school level. Perhaps a similar approach should be adopted for footballers at a similar stage?
However this issue is tackled, the reality is that something needs to be done fast to stop the problem repeating itself.
With so many matches going on each week and the competitive nature of the modern game, the chances are this won't be the last we hear regarding concussion this season.
