Earlier this week, attorneys representing Hernandez refiled a lawsuit against the NFL and its former helmet manufacturer. In the documents, the lawyers claim that the 27-year-old former football player “had a horrendous existence” as a result of a severe chronic traumatic encephalopathy (CTE), which is a degenerative brain disease linked to head trauma.
The complaint, which was obtained by PEOPLE, lays out Hernandez’s estate’s claim that the former New England Patriot sustained multiple hits to the head while wearing Riddell helmets. Hernandez reportedly suffered from Stage 3 CTE from the injuries, which was a rarity in football players at his age.
In April 2017, Hernandez, 27 died by suicide while serving a life without parole for murdering Odin L. Lloyd in North Attleborough in 2013.
The former New England Patriots player was discovered hanging in his cell at the Souza Baranowski Correctional Center in Shirley, Massachusetts.
