Brains of deceased Hall of Famers examined for dementia

The recently deceased half of the Million Dollar Backfield is doing its part to help science.

The brains of Hall of Fame running backs John Henry Johnson and Joe “The Jet” Perry will be examined at Boston University to see if they suffered from dementia created by trauma to the head.

Matt Barrows of the Sacramento Bee reports that Perry’s wife believed he suffered from chronic traumatic encephalopathy, something that has only recently come into focus for football players. Johnson died Friday and Perry passed away in late April.

“He was aware of (the study). He wanted to do it,” Donna Perry told Barrows.

Johnson’s daughter is seeing to it that her father’s brain is also examined. Several current players have pledged to donate their brains for research when they are deceased.
