It's a sad end to a once promising career. According to the Sun-Times, Knox is still walking with a limp 14 months after his spinal fusion operation, and "struggles to sit or stand" comfortably. "I was centimeters away from being paralyzed, so just sitting here and talking, I'm appreciative of that," Knox said Wednesday. "Just the hard work that I had to put in. Just to be able to stay in and do everything in my daily life that I used to do." Only 26 years old, the former fifth-round pick ends his career with 133 catches for 2,214 yards and 12 touchdowns over 45 games.
