Once you reach the top in any sport it is always difficult to stay there as you become the man or women that everyone else wants to beat. That is especially true when it comes to professional boxing and explains why there have only ever been 12 world champion boxers to retire with unbeaten records. The following five are those champions who enjoyed the largest number of fights without a loss in a completed career which included at least one title reign.
5. Jack McAuliffe – 36 Bouts Unbeaten
The world lightweight champion between 1886 and 1893, the Irish-American boxer Jack McAuliffe won 30 of his 36 career bouts, drawing five and having one no decision.
22 of the victories achieved by the so-called ‘Napoleon of the Ring’ were achieved by knockout before McAuliffe retired in 1897. The legendary fighter died some 40 years later on the 5th November 1937 and was inducted into the International Boxing Hall of Fame in 1995.
