When Mike Tyson was dethroned of his heavyweight crown by James "Buster" Douglas in 1990 in a 10th-round knockout in Tokyo, King inserted Giachetti as Tyson's trainer. Giachetti trained Tyson for his next four fights, those against Henry Tillman, Alex Stewart, and the two fights against Donovan "Razor" Ruddock. Giachetti later returned to Tyson's corner for his second fight against Evander Holyfield, the infamous "bite fight".
