My dad told me that he was aware of a fan that died during a game at Lambeau and it was just from excitement..had nothing to do with weather. When my mom was in her 70's. she got so excited about Packer games, she would have to take a Nitoglycerin pill (she had a bad heart).
I doubt if any of you saw this in the live broadcast but in 1970 I was living in Chicago and was watch a Bear-Lion game. All of a sudden a Detroit wide receiver drops dead of a heart attack on the field. Enough morbidity.
I was a senior in high school while watching that game and no pun intended, I thought I was going to have a heart attack. My Dad, who was a huge Packer fan suffered with high blood pressure and heart disease and passed away at the young age of 54 in April of '66 and he, too, had to rely heavily on Nitroglycerin tablets. I watched that game at my Uncle's house {my Dad's twin brother, also a big GB fan who also had the same heart related ailments} and, ironically, I recall him grabbing the bottle of those white Nitro tablets sitting on a table next to him, shaking it and while looking at me, I will never forget to this day him saying, "well, win or lose, I may have to end up taking this whole bottle followed by more Falstaffs." LOL! He made it through that game, the SB that followed, the next season and SB win, plus 20 more seasons. I will always remember spending that Sunday afternoon with my Uncle and watching the "Ice Bowl," the greatest game ever, imho.
The Lion player who was stricken with a heart attack in the final minutes of the game against the Bears and died on the field was Chuck Hughes. He had ran a pass route, although the pass was thrown to another receiver and he collapsed on his way back to the huddle. It was an obvious serious situation of which many probably thought {as did I} he had suffered an injury on the play. I remember that it was Butkus who immediately signaled to the sidelines for medical attention and Hughes was carted off the field. The game was finished in near silence and afterward, the players were informed that he had passed away. No words to describe such a horrible tragedy. To this day, Chuck Hughes remains the only NFL player ever to die on the field during a game.
