I don't have anything that can help you, just a personal memory to share. It was raining hard that day. My wife and had been shopping at the Pontiac Mall [[now Summit Place) and had just returned to the car. I had just turned the radio on, and we hadn't even made it out of the parking lot when it happened. After the play was over the announcer [[I think it was Van Patrick) commented that Chuck was down on the field and wasn't moving. A few seconds later he said Dick Butkus was standing over Chuck and yelling for the medical staff. That's when we knew it might be serious but had no idea how serious.
