CHICAGO -- The family of former Chicago Bears player Dave Duerson filed a wrongful death suit against the NFL on Thursday, claiming the league didn't do enough to prevent or treat the concussions that severely damaged his brain before he killed himself last year.
The suit was filed in Chicago on behalf of Duerson's son, Tregg, and three other children. Duerson died on Feb. 17, 2011, of a self-inflicted gunshot wound to the chest at his home in Sunny Isles Beach, Fla.
