One piece of sport memorabilia that nobody wants.

Today the jockstrap that protected the manhood of boxing legend Joe Frazier 45 years ago when he beat Muhammad Ali hits the auction block.

The jock dates back to what’s known as ‘Ali-Frazier 1′ in 1971, touted at the time as ‘The Fight Of the Century’. After the fight Frazier generously gave the used equipment to his buddy, who held onto it (not literally) for almost 40 years before selling it to a memorabilia dealer in 2009.

Today’s starting bid at GoldinAuctions.com is $5,000.

Best part about the item? It’s never been washed!
