Mike Tyson’s journey to becoming boxing’s most dangerous and dominant competitor in the 1980s was completed on this day, 29 years ago.

‘Iron Mike’ became the first Undisputed Heavyweight Champion since Leon Spinks in 1978 after he beat Tony Tucker via unanimous decision, winning all three judges’ scorecards by the scores of 119–111, 118–113 and 116–112.

The clash at the Las Vegas Hilton pitted two undefeated fighters against each other, although Tyson’s savage punching ability and power was expected to see him through.

A tricky contest ensued against a much-taller opponent, for whom Tyson was unable to knock down to the canvas at any stage.
