PHILADELPHIA (AP) — A judge overseeing thousands of NFL concussion-linked lawsuits says lawyers are still working to address her concerns about a proposed $765 million fund.

U.S. District Judge Anita Brody says she fears the fund may not be large enough to cover up to 20,000 retired players for 65 years.

Lawyers have given her more data to weigh since she rejected the deal on a preliminary basis in January.

The judge says in a Thursday order the parties are continuing to work with the court “to address the issues.” She also has clarified an order this week denying approval of the deal was not a new ruling. She says she was simply adding the January ruling to some case files.

The judge is expected to hold hearings in the case this year.

PHILADELPHIA (AP) — A federal judge in Philadelphia has again declined to approve deals for some of the retired players suing the NFL over concussions.

U.S. District Judge Anita Brody’s preliminary ruling Wednesday affects a batch of lawsuits involving lead plaintiff Kevin Turner, a former Philadelphia Eagle now battling Lou Gehrig’s disease.

Brody had issued a similar ruling in January in the lead case in the matter, which could ultimately cover up to 20,000 retired players.

The judge has asked lawyers for more details to support claims the proposed $765 million fund would last for 65 years. Young players with severe brain injuries would get up to $5 million under the deal, though most players would get far less.

Brody is expected to conduct hearings in the case later this year.
