Rishony, ranked 20th in the world, competed for Israel at the 2016 Summer Olympics in Women's Judo 48 kg, taking the additional place of Europe. In her first bout she was deemed to have illegally touched her opponent’s leg with her elbow in her match against Ukrainian Maryna Cherniak, and was disqualified for illegal use of her elbow at 2:10 of her first bout. After the loss, she admitted "I still don’t understand why I was disqualified." In tears, Rishony said: "I’m still in shock, I felt I was ready and it hurts me that I couldn’t give my all and that it all ended before it really began... I was surprised by the decision of the judge... It’s hard to put in words how much you give and how much you sacrifice and how much you dream of this moment. You certainly don’t imagine it ending like this."
