Jeff Horn, Buster Douglas and Leon Spinks: Boxing's biggest upsets

Updated: 

Manny Pacquiao's best days may be behind him, but his loss to Jeff Horn in Brisbane on Sunday still represented a major shock.

Horn won a unanimous, albeit highly controversial, points decision at Suncorp Stadium to sensationally claim the WBO welterweight world title.

In the wake of the Australian's triumph, we take a look at previous instances where boxers have unexpectedly overcome the odds.

 

July 10, 1951: Turpin shocks Sugar Ray

Widely considered one of the finest boxers in history, Sugar Ray Robinson had only been beaten once - by the great Jake LaMotta - in 132 bouts when he defended his world middleweight crown against Randy Turpin at Earls Court Arena.

Turpin was a virtual unknown, but produced a sensational display over 15 rounds to dethrone Robinson, who gained swift revenge with a knockout triumph when the pair met again in New York two months later.

 

February 15, 1978: 'The Greatest' loses Spinks epic

Muhammad Ali was a 1-10 favourite when he first faced Leon Spinks, a man fighting professionally for only the eighth time, in Las Vegas 39 years ago.

After a titanic battle between boxing's biggest star and his underdog opponent, Ali looked to have done just enough when the first scorecard was read out in his favour.

However, the two remaining judges decided Spinks had done enough, despite conceding almost two stones in weight to Ali. Once again, a rematch produced the opposite result.

 

February 11, 1990: Iron Mike stopped by Buster Douglas

The Tokyo Dome played host to arguably THE biggest boxing upset in history, as Mike Tyson lost his unbeaten record, which had read 37-0 with 33 KOs, to the unheralded Buster Douglas.

Only one casino offered odds on Douglas winning the fight, his price a staggering 42-1. Yet that is what happened, with Tyson left to rue a lack of preparation for a contest he had presumed would prove a breeze. 'Iron Mike' was sent to the canvas in round 10, his aura of invincibility permanently shattered.

 

April 22, 2001: Rahman rocks Lewis

Hasim Rahman spent a month in South Africa, training at high altitude, ahead of his heavyweight world title fight with Lennox Lewis in Gauteng. In contrast, reigning champion Lewis was there only half as long, instead training in Las Vegas so he could film scenes for a cameo appearance in Ocean's 11.

Like Tyson before him, Lewis would pay a heavy price for his apparent over-confidence, as Rahman secured a spectacular knockout victory in the fifth round.

A subsequent rematch saw Rahman beaten in four, with a fiercely focused Lewis earning redemption.
