Former Broncos wide receiver Demaryius Thomas died of “complications of a seizure disorder,” according to the Fulton County (Ga.) Medical Examiner’s report obtained by The Denver Post on Friday.
33-year-old Thomas died last December 9 at his home in Georgia.
Last month, his family announced that Thomas was diagnosed with stage 2 chronic traumatic encephalopathy (CTE) after a brain scan by researchers at Boston University.
Karen Sullivan of the Fulton County Medical Examiner said in her report, citing the Boston University report, “It is not known whether Mr. Thomas’ seizure disorder was of natural causes or the result of blows to the head during his professional career. football player and the medical records reviewed do not have an etiology for Mr. Thomas’s seizures.”
Sullivan wrote that “various physiological events can cause sudden death in individuals with seizure disorders,” and that an abnormal heart rate during or after a seizure can result in death.
Thomas weighed 231 pounds at the time of his death. No other injuries such as a facial fracture were found during the autopsy.
