Tyson v Holyfield
When: 1996
Tyson and Holyfield finally squared off after their original fight had been scuppered by Tyson's arrest and conviction for rape. Both men were four fights into comebacks, although Holyfield was considered a massive underdog.
Refusing to be intimidated by the 'Baddest Man on the Planet' Holyfield kept Tyson on the back foot before stopping Iron Mike in the eleventh, becoming the first person since Ali to win the Heavyweight title three times.
