Hall of Famer Nick Buoniconti, one of the leaders of the Miami Dolphins' undefeated 1972 Super Bowl championship team, has said he'll donate his brain to further the study of concussions after his death.
The 76-year-old former linebacker went public with his health issues in May, telling Sports Illustrated that he sometimes feels "lost" and "like a child" and that he suffers from memory loss and cannot use his left hand, among other ailments.
Doctors confirmed then that he has brain issues that might be linked to playing 14 years of professional football, but Buoniconti then would not say he suffers from CTE.
