Polish javelin thrower Maria Andrejczyk auctioned off her silver medal from the Tokyo Olympics for $125,000 with the goal of using the funds to help an infant receive a life-saving heart surgery.

Andrejczyk explained Wednesday in a Facebook post that she discovered a fundraiser for 8-month-old Miłoszek Małysa. The boy had a serious heart defect and was in need of surgery but the family was looking to attain financial support.

Andrejczyk promptly auctioned off her silver medal from the javelin competition.
