(The Sports Xchange) - Former New England Patriots tight end Aaron Hernandez, who committed suicide in jail while serving a life sentence for murder, had an advanced stage of degenerative brain disease.
Researchers at the Boston University School of Medicine said in a statement Thursday that Hernandez was dealing with chronic traumatic encephalopathy.
Dr. Ann McKee, the director of the school's CTE Center and Chief of Neuropathology at the VA-BU-CLF Brain Bank, said Hernandez had Stage 3 CTE, with Stage 4 the most severe of the disease that has plagued numerous NFL players.
Hernandez's lawyer, Jose Baez, told Deadspin.com that his law firm filed a federal lawsuit against the NFL and the Patriots on behalf of Hernandez's daughter and Shayanna Jenkins-Hernandez, who was engaged to the player at the time of his death.
The lawsuit said Hernandez had "the most severe case of Chronic Traumatic Encephalopathy (CTE) medically seen in a person of his young age of 28 years" by Boston University researchers.
According to the filing, Hernandez's Stage 3 CTE is "usually seen in players with a median age of death of 67 years."

Denver Broncos left tackle Garett Bolles was carted off the field in the middle of the third quarter Sunday with what was expected to be a severe injury.

Chicago Bears guard Kyle Long (ankle) went through a full practice for the first time since the season started, and has been in successive practices this week.
Long is expected to play Sunday against the Pittsburgh Steelers after he practiced Wednesday on a limited basis. How he handles practicing in succession will be a key to whether he's able to play all of Sunday's game.
The Bears are in need of Long's return because right guard Josh Sitton hasn't practiced this week due to a rib injury and backup guard Tom Compton is trying to practice despite a hip injury.
