Bills DT Torell Troup compared his 2012 back injury to the one that ended Johnny Knox's career. Troup says he's fully recovered now, but claimed it was the "same injury" that did in Knox. Troup is now "regularly" doing squats in the weight room and still has a chance to return as an effective NFL player. Specifically, the back injury has been called a "thoracic-lumbar junction fracture dislocation."
