On this day, 35 years ago, on February 11, 1990 (January 16, 1990, the lunar calendar), American boxer Douglas knocked out Tyson and won the title of "Boxing King". On February 11, 1990, Douglas knocked out Tyson in the world heavyweight championship and won the title. James Douglas (born April 7, 1960) is an American boxer. On February 11, 1990, James Douglas knocked down Tyson in 10 rounds in Tokyo, Japan, breaking the biggest upset in boxing history and becoming the world's recognized heavyweight champion. James Douglas neglected to train after defeating Tyson, and was easily ousted from the throne by challenger Holyfield eight months later in very poor form. James Douglas made a comeback in 1996 and achieved several victories, just as Tyson had just recovered from prison. Just as boxing fans were waiting for his second fight with Tyson, on June 25, 1998, he was easily knocked out by then-rookie Savares in the first round of the competition for the vacant IBA heavyweight title. The so-called second fight also disappeared with his defeat.
