Gatineau Olympiques. He was subsequently drafted by the
Los Angeles Kings in the
2012 NHL entry draft but eventually went unsigned. In 2013, Hyka moved to

Anaheim Ducks. He had two shots on net and played 11:37 minutes. Hyka scored his first NHL goal on 23 February 2018 in a game against the
Vancouver Canucks. At the conclusion of his contract with the Golden Knights and unable to cement a full-time role in the NHL, Hyka opted to return to Europe in agreeing to a two-year contract with Russian club,
