One of the most famous power punchers to ever live, Earnie Shavers, passed away on Thursday a day after his 78th birthday.

Shavers amassed a 74-14-1 record between 1969 and 1995, and he was 54-5-1 by 1977 when he earned a world heavyweight title fight against Muhammad Ali at Madison Square Garden.

Shavers lost a 15-round decision to Ali, who famously declared after the fight "Earnie hit me so hard, it shook my kinfolk in Africa".

Fellow heavyweights often spoke of Shavers' power, with George Foreman once telling David Letterman during a late-night talk show conversation about the hardest punchers he ever faced "I never fought Earnie Shavers, thank goodness".

Of his 74 career wins, 68 came by knockout, including 23 in the first round.

Muhammad Ali's championship belt from the Rumble in the Jungle - his 1974 heavyweight title bout with George Foreman - was sold at auction on Sunday for $6.18million.

The belt, won by the legendary boxer after he stopped his rival with an eighth round knockout in Zaire, was purchased by Indianapolis Colts owner Jim Irsay.

The 63-year-old has already purchased a large assortment of pop culture memorabilia, the Isray Collection, which he intends to tour across the nation.

"Proud to be the steward!" Isray tweeted, while revealing the belt would be on display next month in Chicago and then in Indianapolis in September.

Ali's belt falls short of becoming the most expensive piece of sporting memorabilia to be sold at auction.

Diego Maradona's iconic Hand of God shirt - worn during Argentina's quarter-final victory over England at the 1986 FIFA World Cup - fetched just over £7.1m ($8.9m) in May.
