Later that day, you encounter the player as a patient in the Emergency Room where you are working. He is a right-handed fourth-year Engineering student who complains of pain in the right shoulder subsequent to this fall. He is reluctant to abduct or elevate the right arm as he reports that these motions cause pain and a "crunching" feeling. You notice an obvious deformity (see picture below). The patient is most tender just lateral and antero-inferior to the deformity.
