Aaron Hernandez's fiancee Shayanna Jenkins-Hernandez is suing the New England Patriots and the NFL ... claiming the tight end suffered from one of the most severe cases of CTE ever.
Shayanna filed the lawsuit in Mass. on behalf of the daughter she had with Aaron.
In the suit Shayanna says, "Aaron had stage 3 CTE usually seen in players with a median age of death of 67 years."
Shayanna claims the NFL and the Patriots were aware of the link between suicidal impulses and CTE and failed to share that info with Hernandez.
