Tyson's problems outside the ring began to threaten his dominance inside it. Buster Douglas was a 38 to 1 underdog for his bout against Tyson at the Tokyo Dome. Shortly into the fight, however, it quickly became apparent that Tyson's head was elsewhere. Round after round, Douglas chipped away, leading his trainer to shout: "Ain't no iron in Mike! This is your night!"
It certainly was. In the 10th round, Tyson found himself in an unfamiliar position — on the ground, looking up at someone else. His undefeated streak — which numbered 37 before the fight — was smashed. So was Tyson's air of invincibility.
