Devi entered the 2014 Asian Games in Incheon, South Korea, competing in the lightweight category. With a win margin of 3–0 both in the Round of 16 and Quarterfinals, she entered the semifinals to face South Korea's Park Ji-Na on 30 September. After the match, she was handed a 0–3 defeat verdict by the judges of the match, which turned out to be hugely controversial, considering that Devi had knocked Park out in the third round and also a convincing fourth round, before having rained heavy blows on Park throughout the first two rounds. Following this, the Indian team lodged a protest against the decision, which was rejected by the AIBA's technical committee. At the medal awarding ceremony, Devi refused to accept her bronze medal and handed it over to the silver medallist, Park. However, she accepted the medal later. This was followed by provisional suspension of her coaches by the AIBA. She was handed a one-year ban by the AIBA.
