PHILADELPHIA -- A concussion-related lawsuit bringing together scores of cases has been filed in federal court, accusing the NFL of hiding information that linked football-related head trauma to permanent brain injuries.

Lawyers for former players say more than 80 pending lawsuits are consolidated in the "master complaint" filed yesterday in Philadelphia.

Plaintiffs hope to hold the NFL responsible for the care of players suffering from dementia, Alzheimer's disease and other neurological conditions. Other former players remain asymptomatic but worry about the future and want medical monitoring.

The suit accuses the NFL of "mythologizing" and glorifying violence through the media, including its NFL Films division.

"The NFL, like the sport of boxing, was aware of the health risks associated with repetitive blows producing sub-concussive and concussive results and the fact that some members of the NFL player population were at significant risk of developing long-term brain damage and cognitive decline as a result," the complaint charges.

"Despite its knowledge and controlling role in governing player conduct on and off the field, the NFL turned a blind eye to the risk and failed to warn and/or impose safety regulations governing this well-recognized health and safety problem."

The league has denied similar accusations in the past.

"Our legal team will review today's filing," the NFL said in a statement. "The NFL has long made player safety a priority and continues to do so. Any allegation that the NFL sought to mislead players has no merit. It stands in contrast to the league's many actions to better protect players and advance the science and medical understanding of the management and treatment of concussions."

Mary Ann Easterling will remain a plaintiff despite the April suicide of her husband, former Atlanta Falcons safety Ray Easterling, who had been a named plaintiff in a suit filed last year.

Ray Easterling, 62, suffered from undiagnosed dementia for many years that left him angry and volatile, his wife said. He acted out of character, behaving oddly at family parties and making risky business decisions that eventually cost them their home.

The list of notable former players connected to concussion lawsuits is extensive and includes the family of ex-Chicago Bear Dave Duerson, who shot himself last year.

The cases are being consolidated for pretrial issues and discovery before Senior U.S. District Judge Anita B. Brody in Philadelphia.

The problem of concussions in the NFL has moved steadily into the litigation phase for about a year.

According to an AP review of 81 lawsuits filed through May 25, the plaintiffs include 2,138 players who say the NFL did not do enough to inform them about the dangers of head injuries. The total number of plaintiffs in those cases is 3,356, which includes players, spouses and other relatives or representatives.
