Chicago Blackhawks Hall of Famer Bobby Hull had chronic traumatic encephalopathy when he died two years ago, his widow said in a statement released Wednesday.

Chicago Blackhawks legend Bobby Hull lived in a different era than today’s players. The Hall of Fame forward helped the Hawks win the 1961 Stanley Cup during his 15 seasons in Chicago (1957-72) and remains the franchise’s all-time goals leader with 604.

Stanley Cup champion and Hockey Fall of Fame forward Bobby Hull had CTE when he died at 84 in 2023, his widow said in a statement. Researchers at Boston University's CTE Center found that Hull suffered from Stage 2 CTE at the time of his death.
