well iv never been knocked out but i was knocked down once in sparring sort of by a punch but i was off balance but anyways its a weird feeling ur just rele shocked that its happened and ur instant reaction is to get up as quick as posible and i think sometimes fighters try to get up too soon before they have their legs back steady e.g judahs chicken dance look at judah when he got up the second time when the fight was called off around about 8 seconds after the knock down he was fine now he had stayed down to 8 first time he would have been fine
