Why do you call it football if you rarely use your feet? It would be the same if you called handball football.
By the way, clubs are fined and even further action can be taken if found guilty of not taking all precautions possible when handling head injuries. People have died from ignoring such injuries.
I called it American Football. Yes, it's a silly name, yes that is what it is called.
The reason why it is called Football, is because it was originally a form of Football. You see, it all started way back in like the 1860's and early 1870's. US colleges played a form of association football/rugby hybrid. Princeton and Harvard most noticeably. Then in like 1870(something) Harvard played McGill, both schools had their own rules, and McGill introduced the idea of running with the ball, tackling and "downs". Harvard then took the new rules they got from McGill, introduced them to their own rules then went and played Princeton and the rest is history.
The point is, they started with association football, and kept adding stuff till the game was primarily played with the hands. The name was obviously football originally so they just kept it.
To reply to the people suggesting he was "concussed" if he was actually concussed, then he should retire. He will take headers harder than that elbow and if that elbow legitimately concussed him, he is glass chinned and is liable to be rendered completely unconscious fielding a DDG kick.
For the sake of his health and his brain if he was actually concussed he needs to seriously consider retirement.
Or, as I suspect, he was being a vagine, he should grow a pair and get on with it. I'm no stranger to concussions myself, and yes they suck, it took me almost 8 years to finally stop getting what doctors consider post concussion migraines. However, there is absolutely no normal person that would a concussion or be concussed from that blow.
