The death of former Chicago Bears safety Dave Duerson was ruled a suicide by the Miami-Dade County Medical Examiner, WMAQ-TV in Chicago reported Saturday.
Duerson was found dead Thursday night at his home in Miami. The Miami-Dade County Medical Examiner said he died from a gunshot wound to the chest.
In a text message he sent to loved ones before his death, Duerson asked that his brain, particularly the “left side,” be left for NFL researchers who study chronic traumatic encephalopathy (CTE), a degenerative disease common to boxers, football players and others who experience multiple concussions and head injuries.
Duerson, 50, starred at Notre Dame and played for the legendary Bears defense that powered the team to a victory in Super Bowl XX. He was elected to four straight Pro Bowls from 1986-89 and also won a second Super Bowl with the 1990 Giants.
