The jockstrap responsible for protecting boxing legend Joe Frazier’s manhood 45 years past, when he defeated Muhammad Ali, will be auctioned off.

Dating back to 1971, the jockstrap was part of one of the most significant sporting events in America’s history. Frazier was pronounced the victor in an unanimous decision.

That same night, Frazier gave his pal the jockstrap, who kept a hold of it for nearly 40 years, then sold it in 2009 to a dealer in memorabilia. The collector has joined with Goldin Auctions, now putting the extremely rare item up for auction. The opening bid is set at $5,000.

By the way, a jockstrap that was worn by Hall-of-Famer Nolan Ryan was reportedly sold at $25,000.

And the best part about it is the jockstrap hasn’t been washed!
