jovan belcher *The death of Kansas City Chiefs player Jovan Belcher is the latest in a string of suicides by current or former NFL players.

Some are theorizing that his life-taking actions – like the others – were the result of concussions. However, the team says Belcher did not have a history of concussions.

It’s not yet clear what prompted Belcher’s actions, but his suicide follows those of former NFL players Junior Seau, 43, and Dave Duerson, 50, both of whom died of self-inflicted gunshot wounds to the chest in the last two years.

The suicides of Seau, Duerson and a number of other NFL players have been blamed on concussions racked up from playing the violent sport, and a condition called chronic traumatic encephalopathy, or CTE, but that may not be the case for Belcher.

Chiefs chairman Clark Hunt said today that Belcher was “a player who had not had a long concussion history,” even though he was a three-time all-America wrestler and a star on the football team at his West Babylon, N.Y., high school.
