Football is a violent sport. For the last four years, about three hundred players per year suffered season-ending injuries that put them on the Injured Reserve (IR) list. These players suffer injuries that you can’t tape up and there’s no way to ‘play through the pain’. For the most part, these are serious, career threatening injuries. A recent study published in the Foot & Ankle Specialist found that more than a third of the NFL players who suffered an Achilles tendon injury were unable to return to the NFL. Those who did resume professional play saw their power ratings drop by an average of 50%.
