PHILADELPHIA, PA -  The potential $1 billion settlement of NFL concussion claims appears close to winning final approval.

U.S. District Judge Anita Brody in Philadelphia has asked for only a few tweaks from the two sides this week.

The settlement would resolve thousands of lawsuits that accuse the NFL of hiding what it knew about the link between concussions and long-term brain injury.

The lead lawyers say the deal gets money more quickly to struggling ex-players as they deal with dementia and other health problems.

But critics say it doesn't go far enough to help men battling depression and mood disorders.

Eleanor Perfetto of Annapolis, Maryland, says it's hard to calculate what she might get for husband Ralph Wenzel's early death from Alzheimer's disease.

Brody has already granted preliminary approval of the deal. The final revisions are due Friday.
