The NFL settled a class action lawsuit from former players suing the league over concussions, but not every player was included.

Former Chicago Bears safety Craig Steltz started his own suit against the NFL because of the traumatic brain injuries he suffered while playing professional football, according to the New Orleans Advocate.

The class action settlement paid out $1 billion to end former players’ claims, but that only covered players who stopped playing by the end of July of 2014.

Steltz was released by the Bears and ended his career in August of 2014, making him ineligible for the initial suit and leading him to file his own.

A fourth-round pick in 2008, he spent six years in Chicago, starting only eight games but contributing regularly on special teams.

Other recently retired players may be watching the Steltz case closely to see how the NFL handles their former athletes who missed the cutoff date for the initial class action suit.
