Suicides of some other NFL players have involved brain injuries
(CNN) -- Paul Oliver, a former defensive back for the University of Georgia and the San Diego Chargers, was found dead this week, apparently from a self-inflicted gunshot.
His death marks the latest in a string of suicides among former professional football players.
"Everyone in the Chargers family is sad today after hearing the news about Paul," a statement from the NFL team said. "He was part of our family for five years. At just 29 years old, he still had a lifetime in front of him. Right now all of our thoughts and prayers are with his family during this most difficult time."
Star NFL linebacker Junior Seau was 43 when he took his own life in May 2012. The National Institutes of Health later found he suffered from chronic traumatic encephalopathy, or CTE, a neurodegenerative brain disease that can follow multiple hits to the head.
A study published in December in the journal Brain looked at brain tissue of 34 professional football players after they died. All but oneshowed evidence of disease.
In April 2012, former Atlanta Falcons safety Ray Easterling, 62, committed suicide. An autopsy found signs of CTE.
In February 2011, former Chicago Bears defensive back Dave Duerson, 50, committed suicide with a gunshot to the chest, rather than his head, so his brain could be researched for CTE. Boston University researchers found the disease in his brain.
In December 2012, Jovan Belcher of the Kansas City Chiefs killed his girlfriend before taking his own life. His remains were not tested for CTE, media reports said.
The NFL launched a crisis support line in July 2012 for players, former players and their families. Called NFL Life Line, it operates independently from the NFL and promises to keep all calls confidential.
"There is no higher priority for the National Football League than the health and wellness of our players," NFL Commissioner Roger Goodell wrote in a letter to personnel and fans at the time.
