Nowinski played a role in the discovery of the fourth case of chronic traumatic encephalopathy (CTE) in a former NFL football player, former Pittsburgh Steelers offensive lineman Justin Strzelczyk, who was killed in an automobile crash in 2004 at age 36. Julian Bailes, the chairman of the department of neurosurgery at West Virginia University and the Steelers' team neurosurgeon during Strzelczyk's career, insisted to Nowinski over a phone conversation that he thought Strzelczyk's death, which was precipitated by strange behavior that some had labeled as "bipolar", was worth looking into due to its similarities to the Andre Waters case. Nowinski contacted Omalu, who discovered the brain was still available, and Nowinski called Mary Strzelczyk, Justin's mother, to ask for permission to Omalu to examine it for CTE. Omalu's positive diagnosis was confirmed by two other neuropathologists.
