The league has now fully embraced researchers it has long sought to discredit:
“It’s quite obvious from the medical research that’s been done that concussions can lead to long-term problems,” the league spokesman Greg Aiello said in a telephone interview. He was discussing how the league could donate $1 million or more to the Center for the Study of Traumatic Encephalopathy at Boston University, whose discoveries of brain damage commonly associated with boxers in the brains of deceased football players were regularly discredited by the N.F.L.
Told that his statement was the first time any league official had publicly acknowledged any long-term effects of concussions, and that it contradicted past statements made by the league, its doctors and literature currently given to players, Aiello said: “We all share the same interest. That’s as much as I’m going to say.”
