The judge presiding over thousands of NFL concussion lawsuits wants lawyers to tweak the proposed settlement to benefit more retired players.
Senior U.S. District Judge Anita Brody in Philadelphia is considering a plan that could pay out $1 billion over 65 years.
Brody has granted preliminary approval but asked Monday that players get credit for time spent with NFL Europe. She also wants families to have more time to file for deaths involving traumatic brain injury.
Brody has asked the NFL and players' lawyers to file revisions by Feb. 13.
The NFL expects 6,000 of nearly 20,000 retired players to suffer from Alzheimer's disease or moderate dementia someday.
Critics say former players exhibiting mood disorders would be left out of the settlement, but Brody did not reference those concerns Monday.
