Michael Gerard ‘Mike’ Tyson made his professional boxing debut, as an 18-year-old, on March 6, 1985 and the following November knocked out Trevor Berbick to become World Boxing Council (WBC) heavyweight champion. In his 58-fight career, ‘Iron Mike’ won 50 fights, 44 of them by knockout, and became undisputed world heavyweight champion. However, he did lose six times, three times by knockout, twice by technical knockout and once by disqualification.
His first knockout came at the hands of the unheralded James ‘Buster’ Douglas on February 11, 1990. In one of the biggest shocks in modern sporting history, Douglas recovered from an eighth-round knockdown to knock out Tyson – who had never previously hit the canvas – early in the tenth round and bring his hitherto unbeaten record to an end. Although he suffered a surprising loss, by technical knockout, to Evander Holyfield in November, 1996 and another, less surprisingly, by disqualification – after he bit Holyfield twice on his right ear, severely enough to remove part of it – in their rematch six months later, Tyson was only ever knocked out twice more.
In what became, ultimately, a one-sided contest against undisputed heavyweight champion Lennox Lewis on June 8, 2003, Tyson was eventually knocked down, and out, in the eighth round. The following July, facing debts of $38 million, Tyson returned to the ring for what proved to be the penultimate fight of his career against former British Commonwealth heavyweight champion Danny ‘The Brixton Bomber’ Williams. In the fourth round, Williams unleashed a flurry of unanswered punches, culminating with a huge right hand, which sent Tyson reeling. Tyson sat, dazed, on the canvas, leaning against the ropes and, although he did eventually try to get to his feet, was counted out.
