Kupp needs to adjust his training routine coming back from this injury. His injury occurred when he planted his leg before breaking on his route; it was caused by the shearing force at the joint as a result of deceleration. I run on a masters track and cross country team and our coach has us run infinity drills which is basically running in the pattern of a figure 8. This does a few things including improving proprioception so that you move from your core and don't get the eccentric forces in the joints. Jimmy Garappolo's knee injury was the result of him making a cut without having his core, his center of mass, under control.
