This guy punched harder than Tyson
Ruiz turned professional as a cruiserweight in 1992 before moving into the heavyweight division two years later. His first major fight came against contender David Tua in March 1996 on HBO. It was a bitterly disappointing performance for Ruiz, who was severely knocked out in just 19 seconds.
Ruiz spent years trying to live down that knockout, which he eventually did.
