America rages at Aussie boxing fans over Haney-Kambosos 'disgrace'

Australian boxing fans have been condemned in America after some booed the US national anthem ahead of George Kambosos' lightweight fight with Devin Haney in Melbourne.

Kambosos Jr relinquished his three world title belts after a unanimous defeat to his American opponent in their lightweight blockbuster on Sunday.

HUGE: Boxing fans in frenzy over Tim Tszyu announcement

Haney inflicted Kambosos with the first loss of his 21-fight career at Marvel Stadium to add the WBA, WBO and IBF titles to the WBC strap he already held.

The 23-year-old joins an exclusive club of seven fighters, including legends Bernard Hopkins, Terence Crawford and Tim Tszyu's looming opponent Jermell Charlo, to unify a division in the 18-year four-belt era.

While the fight was somewhat underwhelming, there were unsavoury scenes before the bout when a number of fans in attendance loudly booed the American national anthem.

Haney was also booed by Aussie fans when he made his walk to the ring, leaving American TV viewers fuming.

US sports writer Dan Clark tweeted: "Complete miss-match of a fight. George Kambosos looks slow, uninspired, unfit, and in a completely different class to the wonderful Devin Haney."

"Shame on the Australian crowd for the 'boos' during the US national anthem earlier too. Now, complete silence."

Others described those booing as 'embarrassing' and 'shameful'.

Devin Haney takes George Kambosos' world titles

Two of the judges awarded the bout 116-112 to Haney, with the third giving it 118-110 to The Dream from Las Vegas.

The new undisputed lightweight champion improved his unbeaten record to 28 wins with a pure display of boxing in the biggest fight ever on Australian shores.

While Kambosos landed the heavier blows throughout the 12-round contest, Haney peppered the home hope with left jabs to win over the judges.

The two combatants barely threw a punch in a watchful opening round that Kambosos may have stolen with a late combination to the American's body.

Kambosos landed the first big punch of the fight, a heavy right to Haney's head, in the second as the Australian had his challenger retreating.

A more aggressive Haney took the third round with a series of left jabs and looked to have also shaded the fourth before Kambosos delivered a big left hook late.

Kambosos landed another strong, much-needed left in the sixth round as Haney's peppering jab began to show on the Australian's face.

Haney controlled rounds seven and eight, leaving Kambosos to find something to sway the judges.

He did so, the Greek-Australian spartan warrior landing three big rights to take the ninth round as the home crowd of almost 50,000 fans willed their local hero to dig deep.

However it wasn't enough as Haney was crowned the unanimous winner and undisputed lightweight world champion.

"He had a smart game plan. He grabbed and held a lot but he did what he had to do to win and that's what it's about," Kambosos said after the fight.

"Today they gave him the decision but I'm sure that will change when we get it on again."
