VILLANOVA, Pa. (AP) — The court fight over NFL concussions should heat up soon when a judge in Philadelphia weighs the fairness of the proposed $765 million settlement.

Lead players’ lawyer Sol Weiss expects the judge’s financial expert to advise her “shortly” on his view of the plan.

Senior U.S. District Judge Anita Brody will then hold a fairness hearing, when financial details will emerge.

Brody is concerned the fund won’t cover 20,000 retirees for 65 years. And critics say the NFL, with $9 billion in revenues, is getting off lightly.

The program would pay retirees as much as $5 million for the most serious neurological injuries.

Speaking Friday at Villanova University outside Philadelphia, Weiss says he’s confident the fund is sufficient. He believes most players will sign on rather than fight the NFL in court.
