Dan Rafael reports via Twitter that former world heavyweight champion Mike Tyson will ring the bell for tonight's ten-bell salute to another former world heavyweight champion, the late Smokin' Joe Frazier.
Frazier passed away on Monday after a battle with liver cancer, at the age of 67. His death was major international news, and not just in the sports world. Frazier's 1970s trilogy with Muhammad Ali is considered one of the great rivalries in all of sports history, and had a cultural impact that we're unlikely to ever see again in the boxing world.
The Pacquiao vs Marquez card is the first really major boxing event to take place in the United States since Frazier's passing. HBO will also tribute Frazier during the pay-per-view tonight, and you can also watch their Thrilla in Manila documentary today and through November 27 with HBO on Demand. For those who haven't seen it, it's a recommended viewing.
