Legendary World Wrestling Entertainment manager and commentator Bobby "The Brain" Heenan died Sunday at age 73, reports ESPN, which calls Heenan "one of the most renowned managers and commentators in the history of professional wrestling." A cause of death hasn't been confirmed, but Heenan had been fighting throat and tongue cancer since 2002. Heenan came to the WWE in 1984 after first working with other wrestling organizations; he ended up building the "Heenan Family," a group of wrestlers he managed that included such big names as Andre the Giant and Ric Flair. He also went on to have massive success as a commentator after retiring as a manager in the '90s, and WWE exec Triple H tells TMZ Heenan was also an extremely talented wrestler—he simply "wanted to be a manager," Triple H says. "That's what he wanted to do."
Heenan left WWE in 1994 for World Championship Wrestling, but he returned to the WWE when Vince McMahon bought out WCW in 2001. He was inducted into the WWE Hall of Fame three years later. McMahon and Flair were among those mourning Heenan on Twitter, with Flair calling him "The Greatest Manager, One Of The Greatest Announcers, And One Of The Best In-Ring Performers In The History Of The Business" and McMahon calling him "One of the greatest managers and announcers in WWE history." UPROXX rounds up some of Heenan's greatest quotes, including: "I know all about cheating. I've had six very successful marriages." The truth? He was married just once, in 1974. In addition to wife Cynthia Jean, he leaves behind a daughter and a grandson, the Los Angeles Times reports.
