An Olympic discus thrower has auctioned off his silver medal to raise money for a child's cancer treatment.
According to ESPN, the medal auction had raised around $19,000 when it ended on Tuesday.
The discus thrower says the funds he gets from the the auction will go directly to Olek's treatment. The Olympian wrote: "In Rio, I fought for gold. Today, I appeal to all — let's fight together for something that is even more valuable. The health of this fantastic boy."
Malachowski isn't the only Olympian to auction off his medal for a cause. U.S. swimmer Anthony Ervin sold his to bolster aid relief efforts after the 2004 Indian Ocean tsunami. And famed Ukrainian boxer Wladimir Klitschko sold his medal from the 1996 Atlanta Olympics for more than $1 million as part of a fundraising event for his children's charity.
