BOSTON -- (WBZ) -- Aaron Hernandez's family has filed a federal lawsuit against the NFL and the New England Patriots after tests on the former player brain revealed a “severe case” of brain trauma.
Attorney Jose Baez announced Thursday afternoon that tests performed on Aaron Hernandez's brain following his suicide determined he suffered from an advanced case of Chronic Traumatic Encephalopathy (CTE).
The lawsuit has been filed on behalf of Hernandez's daughter.
Baez said Boston University researchers said it was “the most severe case they had ever seen for someone of Aaron's age.”
Hernandez suffered from stage three CTE, a level usually seen in brain trauma patients who are 67 years old. There are four stages of CTE.
