NFL official links football, CTE; could it affect $1B deal? (Yahoo Sports)

Critics of the NFL's proposed $1 billion plan to settle concussion claims say a league official's acknowledgement of a link between football and the brain disease CTE is a game changer. A federal appeals court in Philadelphia is weighing a challenge to the settlement that would exclude future cases of chronic traumatic encephalopathy, or CTE. Critics want the plan expanded to include future CTE cases.
