We learned on Sunday that Kansas City Chiefs wide receiver Tyreek Hill suffered a posterior SC (sternoclavicular) dislocation. There are two basic types of this injury: anterior (forward away from the body) and posterior (backward, toward the body). Hill suffered the latter version.

As seen above, the SC joint is where your sternum and collarbone meet. Very little movement occurs here, but it is a crucial piece of how your shoulder moves.
