The NFL, for the first time, acknowledged there is a link between football-related head trauma and chronic traumatic encephalopathy, or CTE.
Albert Haynesworth, the former Titans and Redskins defensive tackle, said he had two brain aneurysms in 2014 that nearly killed him, adding that he struggles with memory loss.
Former NFL quarterback Ken Stabler had CTE when he died in 2015, the doctor who examined his brain told ESPN's Outside The Lines.

The family of Lawrence Phillips will donate his brain to chronic traumatic encephalopathy researchers in a quest for answers, their attorney told USA Today Sports.
