The biggest upset boxing has ever seen 📖 In 1990, James ‘Buster’ Douglas walked into Tokyo a 42-to-1 underdog against the undefeated and feared Mike Tyson — and left with the heavyweight championship. After surviving an 8th-round knockdown, Douglas rallied back and dropped Tyson in the 10th with a vicious uppercut–hook combo. Tyson couldn’t beat the count. The invincible aura was gone. That night, Buster Douglas shocked the world — and made history. All in honor of his mother.
