The amended complaint filed in Miami federal court contends Stabler and others were left out of the NFL’s $1 billion concussion settlement because of an April 2015 cutoff date.

Stabler died in July 2015 from colon cancer, but the lawsuit says he also suffered from chronic brain damage.

The lawsuit seeks unspecified damages and class action status to represent other players in similar situations.

Stabler was elected to the Hall of Fame this year. He played for the Oakland Raiders, Houston Oilers and New Orleans Saints.
