Who is the only heavyweight boxing champion to retire with an undefeated record? Correct

The only heavyweight boxing champion to retire with an undefeated record is Rocky Marciano. While Mike Tyson, Joe Louis, and Muhammad Ali are all legendary figures in the world of boxing, it was Rocky Marciano who achieved the remarkable feat of retiring with a perfect record. Marciano, known as “The Brockton Blockbuster,” compiled a record of 49 wins with no losses and 43 knockouts during his career, culminating in his retirement as the only heavyweight champion to accomplish such a feat. His unbeaten record and aggressive fighting style have solidified his legacy as one of the greatest boxers in the history of the sport.
