When one of his soccer teammates can't catch his breath, Michael convinces him to seek treatment at the clinic. But with frequent trips to Indonesia on his schedule and a history of IV drug use, the possibility of a sobering diagnosis is very real - especially when he starts coughing up blood. Michael's friend also has a fear of doctors, and he flees the clinic before Kate can figure out what's wrong with him. While she runs a test for TB, Michael must seek out his teammate and try to get him to submit to further help. While at the clinic, Michael runs into a former patent of his - an ex-NFL star whom he performed successful spinal chord surgery on years ago. The player is now a shell of his former self, living on the street without the brainpower to even remember his own name. While there is no known cure for a brain turned to mush by thousands of high-speed football collisions, Michael takes him back to Holt Neuro in order to try. Michael also examines the seventeen-year-old daughter of one of his colleagues who appears to have suffered a concussion in a bathroom accident. But during the session, Michael begins to suspect that the injury was self inflicted.
