Biggest Upset In Boxing History - What Was It?

[Vivid Intent]

Great win for Buster but Mike really knocked him out in the 8th.

douglas vs Tyson by far because at 1st Douglas was a 40:1 underdog & was a handpicked EASY fight instead of giving ruddock his title shot in Edmonton.Tyson got floored by greg page here in Edmonton & stormed out of the gym.when greg page floored him sparring it was the first sign of vulnerability Tyson ever had...he was never the same after the Douglas fight but it was greg page who started the downfall.

Buster Douglas over Iron Mike.....

[Super Horny]

marquez defeats mayweather. it ain't happened yet but it will.

[D-MiZe]

Douglas beating Mike isn't really a genuine upset though. Considering what Tyson was doing when he was supposed to be training.

Are there any genuine upsets where both fighters trained as hard as normal but the higher rated fighter lost?

Pac man vs De La Hoya

[Sugarj]

Heres a few random additions, some where the favorite may have won but the manner was unexpected:

Lloyd Honeyghan vs Don Curry

Tarver vs Jones 2 ( Who honestly thought Jones would get KOd in 2? )

Hearns vs Duran ( Who'd have thought the Duran who went a close 15 rounds with Hager would get KOd in 2?)

Holyfield vs Tyson 1 ( Some casinos had this 33:1!!!)

Liston vs Ali 1 ( No one gave the young Clay a prayer )

Foreman vs Ali ( Few gave the old Ali a prayer!! )

Schmelling vs Louis 1

Corbett vs L' Sullivan

Randall vs Chavez

[Abstraction]

Tyson v Douglas was one at time.

But considering later on people learnt how he neglected his training, and his problems with Don King, his Ex-Wife etc. came to light.

It made alot more sense

[Pugilistic™]

Tyson - Douglas has to be number 1 imo.
