He never lost a bout, and posted a career record of 49 wins, including 43 knockouts. He was known for his "relentless fighting style," "iron chin", and stamina. His nearly 90 percent win-to-knockout ratio remains one of the highest ever, and he successfully defended his heavyweight title six times. Below is a listing of his perfect career record.
