Former NFL Star Brett Favre played in a ton of games during his illustrious 20 year career, but during his last play ever, he had an “eye opening experience” after suffering a scary concussion.

“It was really the first time I had ever really gone to sleep, if you will, on the turf,” he told the FOX Business Network’s Maria Bartiromo.  “Fifteen or so seconds later I had woken up and I knew what had taken place… it was a scary experience  because concussion talk had just kind of started getting really hot at that time.”
