The death of former NFL linebacker Parys Haralson was ruled to have been caused by a stroke, according to Tom Schad of USA Today on Thursday.
The San Francisco 49ers announced Haralson died at his home in September at the age of 37, with the team saying it was "shocked by the news."
The Santa Clara County Medical Examiner-Coroner’s Office ruled it a natural death and that a "rupture of (a) cerebrovascular malformation" led to a stroke.
The autopsy report noted that Haralson had a "history of multiple concussions" during his football career, but it was not listed as a contributing factor in his death.
