Shorts worn by Muhammad Ali at the 'Thrilla in Manila' could fetch up to $6MILLION at auction... as a collection of championship sports memorabilia is sold off at Sotheby's

A special pair of boxing shorts worn by 'The Greatest' to ever step in a ring could fetch some big bucks at auction in the coming days.

Muhammad Ali's trunks that he wore at the 'Thrilla in Manila' against Joe Frazier- one of the most storied fights in boxing history - are up for sale at Sotheby's in New York City.

With the current bid on the iconic piece of memorabilia sitting at $3.8million, Sotheby's believes that it could fetch in a range between four and six million dollars by the time the lot closes on April 12.

The bout is universally regarded as one of the greatest and most brutal fights in the history of professional boxing - going 14 rounds in sweltering 120°F (49°C) heat.

It ended after Frazier's corner men told the referee to stop the fight.

The fight between the then-heavyweight champion Ali and Joe Frazier is one of boxing's best

It ended in the 14th round after a strong display by Ali led to Frazier's corner ending the fight

Frazier's trainer, Eddie Futch, decided to call the fight after seeing the results of the 14th round - where Ali hit him with a flurry of punches - that left 'Smokin' Joe' barely able to see.

Unbeknownst to Frazier's corner, Ali was also about to retire - after instructing his trainers to cut off his gloves.

He later told biographer Thomas Hauser, 'Frazier quit just before I did. I didn't think I could fight anymore.'

A friend of Frazier's who was at the fight, Denise Menz, later described the atmosphere in the Araneta Coliseum as 'So intensely hot, I've never before felt heat like that in my life. Not a breath of air—nothing. And that was sitting there. Can you imagine being in the ring? I don't know how they did it.'

It was the third and final fight between the two boxing legends - giving Ali a 2-1 advantage over Frazier and retaining his three heavyweight championship belts.
