World Wrestling Entertainment Inc. (WWE) Hall of Famer Bobby “The Brain” Heenan died on Sunday, according to WWE.

Heenan, 73, who worked as a wrestler, professional wrestling manager and commentator for more than 40 years, was “regarded by many as the greatest manager in sports-entertainment history,” the WWE said in a statement.
