Wow, crazy stuff. Strong was one of the best FBs ever to play the game. http://www.nfl.com/news/story?id=09000d5d8031778f&template=with-video&confirm=true Posted: 3 hours 55 minutes ago Neck injury will end the career of Seahawks fullback Strong NFL.com KIRKLAND, Wash. -- Seattle Seahawks fullback Mack Strong has a spinal cord condition that is ending his career immediately -- but not affecting his quality of life. And for that, the 36-year-old Pro Bowler, husband and father of two is grateful. "I've played a long time, 15 years. I felt like I was pretty lucky, pretty blessed," a teary-eyed Strong said Monday after learning that a herniated disk in his neck is pinching his spinal cord -- and ending an unheralded, improbable career that began as an undrafted free agent out of Georgia in 1993.
