(NEW YORK) — New research is strengthening the link between long-term brain damage and playing football.
ESPN and PBS’ Frontline are working on a documentary and report that scientists have discovered 28 new cases of chronic brain disease in football players who have died — 15 of them, former NFL players.
One researcher says the sheer volume of cases proves no one can deny there’s a problem.
