The likes of Mike Tyson and Lennox Lewis have also suffered huge defeats in their careers
5. George Foreman defeat Michael Moorer – 1994
On October 29, 1974, George Foreman defended the heavyweight championship of the world against Muhammad Ali in Kinshasa at “The Rumble in the Jungle,” a fight that would rightly achieve legendary status and go down as one of the most monumental events in boxing history.
4. Cassisus Clay defeat Sonny Liston – 1964
Liston was a boxing enigma, known for his toughness, punching power, strength and large hands, he had only been beaten once and was heavyweight champion heading into this bout, having destroyed Floyd Patterson for the belts in one round.
Clay (before he became Ali) was a fast-talking, confident 22-year-old, who continuously taunted Liston, boasting he would knock him out in eight.
4. Hasim Rahman defeat Lennox Lewis – 2001
When Lennox Lewis travelled to Brakpan, South Africa to face relative unknown Hasim Rahman he must have thought it was just another defence of his crown that would earn him some more money and keep him going towards retirement.
2. Anthony Joshua was beaten by Andy Ruiz Jr in one of the greatest upsets in sporting history, let alone boxing – 2019
Anthony Joshua lost his WBA, IBF and WBO heavyweight world titles as he was stopped by rank outsider Ruiz at Madison Square Garden in the early hours of Sunday morning on his US debut.
1. Mike Tyson‘s defeat by James ‘Buster’ Douglas in February 1990 is one of boxing’s biggest shocks
James “Buster” Douglas uppercut had nearly separated head from body. A follow-up flurry had put Tyson to the mat for the first time in his professional career. Things weren’t going so well.
