Dr. Anahi (AN'-ih-hee) Ortiz of Franklin County says the examination by an Ohio State neuropathologist is being done because Kosta Karageorge (KOH'-stah KAHR'-ah-jorj) had a reported history of multiple concussions.
Ortiz said Monday that an autopsy determined the 22-year-old Karageorge died of a gunshot wound, but she hasn't yet definitively ruled it a suicide.
Columbus police said Sunday that Karageorge died of an apparent self-inflicted gunshot wound.
His mother, Susan Karageorge, told police in a missing-person's report that her son had had several concussions.
Karageorge was a wrestler for three years and joined the football team as a walk-on this season.
