LOS ANGELES (AP) -- Seventy-five former players are suing the National Football League, claiming the league concealed information about the danger of concussions for decades.
The negligence and liability suit filed Tuesday in Los Angeles Superior Court lists Raymond Clayborn, Ottis Anderson and Mark Duper as plaintiffs, among others. Most players listed their wives as co-plaintiffs.
Helmet maker Riddell also is a defendant.
The suit alleges the NFL knew as early as the 1920s of the harmful effects of concussions and claims that information was concealed from coaches, trainers, players and the public until June 2010.
NFL spokesman Greg Aiello says the league hasn't seen the suit but would "vigorously" contest any claims of that kind.
