Muhammad Ali’s championship belt from his 1974 “Rumble in the Jungle” heavyweight title fight was sold at auction on Sunday for $6.18 million.
The winner of the heated competition for the belt was Indianapolis Colts owner Jim Irsay, according to Heritage Auctions in Dallas.
In a tweet Sunday, Irsay confirmed he acquired the belt for his collection of rock music, American history and pop culture memorabilia that is currently touring the country.
The belt will be displayed on Aug. 2 at Chicago’s Navy Pier and on Sept. 9 in Indianapolis.
“Proud to be the steward!” Irsay tweeted.
“After several hours of watching two bidders go back and forth over this belt, this proved to be a battle worthy of the Rumble itself,” Chris Ivy, Heritage’s director of sports auctions, said in a statement.
Ivy did not disclose the name of the person who competed against Irsay.
The 1974 fight was one of boxing’s most memorable moments. Ali stopped the fearsome George Foreman to recapture the heavyweight title in the African nation of Zaire. Ali won the fight in a knockout in the eighth round.
This belt joins other Ali artifacts in the Irsay collection, including Ali’s 1965 walkout robe that first bore his new name, his shoes from the 1975 “Thrilla’ in Manilla” vs. Joe Frazier, and his fight-worn gloves from a 1966 title defense in Germany.
