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.
