In the 1970's a player died on the field of a football game due i think to cardiac arrest (have not looked up the particulars), they carted him off, then resumed play.
patriots preseason darryl stingly, got Demolished- broke his neck, permanently paralyzed from neck down, carted off, resumed game.
etc.
the mentality of football players is ,,,keep playing. which is why i don't agree with the hate diggs was getting about him trying to get his team mates back into football mind set. because he thought- like probably most of the players on the field- the game will continue, once the game was called, he was the First player to the hospital.
