A federal judge on Monday granted preliminary approval to a landmark deal that would compensate thousands of former NFL players for concussion-related claims. The ruling by U.S. District Judge Anita Brody in Philadelphia came about two weeks after the NFL agreed to remove a $675 million cap on damages.

Brody had previously questioned whether that would be enough money to pay all claims. "A class action settlement that offers prompt relief is superior to the likely alternative — years of expensive, difficult, and uncertain litigation, with no assurance of recovery, while retired players' physical and mental conditions continue to deteriorate," Brody wrote.

More than 4,500 former players have filed suit, some accusing the league of fraud for its handling of concussions. They include former Dallas Cowboys running back Tony Dorsett and Super Bowl-winning Chicago Bears quarterback Jim McMahon, who suffers from dementia.

The settlement is designed to last at least 65 years and give $1 million or more to retirees who develop Lou Gehrig's disease and other profound neurological problems.
