Bobby Hull, the former NHL legend with the Chicago Blackhawks, is part of an unfortunate trend being exposed in hockey with regards to CTE.

He insisted on donating his brain,” said Deborah Hull, Bobby Hull’s wife of almost 40 years, “feeling as though it was his duty to help advance research on this agonizing disease.”

Bobby Hull's widow says the Hall of Famer and two-time NHL MVP who helped the Chicago Blackhawks win the 1961 Stanley Cup had chronic traumatic encephalopathy when he died two years ago.
