PHILADELPHIA -- A federal court hearing in Philadelphia could determine whether the NFL faces years of litigation over concussion-related brain injuries.
Thousands of former players have accused league officials of concealing what they knew about the risk of playing after a concussion.
The lawsuits allege the league glorified violence as the game became a $9 billion-a-year industry.
Some former players suffer from dementia, depression and other brain diseases, and a few have committed suicide. Others are seeking medical monitoring.
The NFL denies any fraud or negligence, and insists that player safety has always been a priority.
The league believes the complaints should go to arbitration under terms of a union contract.
U.S. District Judge Anita Brody will hear arguments Tuesday morning from Supreme Court litigators Paul Clement for the NFL and David Frederick for the players.
The hearing begins at 10 a.m.
