"Marvelous Marvin Hagler has been an inspiration and a source of civic pride for Brockton for generations," Sullivan said in a statement. "He is one of the primary reasons why we are known as the ‘City of Champions.’ This public memorial will be a fitting tribute to one of our city’s favorite sons and one of boxing’s all-time greats.” The event, scheduled for 2 p.m. at Marciano Stadium, will feature several celebrity guests and speakers, including legendary boxing champion Bernard Hopkins, ESPN host Stephen A. Smith, Showtime Championship Boxing analyst Al Bernstein, WCVB Channel 5 sports anchor Mike Lynch, acclaimed boxing writer and historian Ron Borges and members of the Hagler family.
