Jersey Joe Walcott vs Rocky Marciano I

Jersey Joe Walcott defends the heavyweight championship of the world against 'The Brockton Blockbuster', Rocky Marciano. This was Walcott's second defense of the title. Because of his advanced age he was the underdog, but was still far ahead before the KO. There would therefore be a rematch the following year.
